STNews - July 2011


CA Sections Added to ACS Publications Web Editions Platform

CAS and ACS Publications have collaborated to map the 80 sections fo Chemical AbstractsTM (CA) to tables of contents, abstracts and article-level content displays on the ACS Publications Web Editions platform.

Articles across the 39 scholarly research journals published by the Society, including Journal of the American Chemical Society, are now tagged with CA section subjects. Incorporation of CA sections enables browsing and discovery of cutting-edge research results from the nearly 500,000 articles published in ACS peer-reviewed journals between 1996 and 2011.

STN Adds Australian Patent Full-text File, AUPATFULL, Including the New Numeric Search Feature

AUPATFULL is a new patent full-text database on STN as of July 24, 2011. It provides the full-text of patent applications and patent specifications published by the Australian Patent Office from 1964 onwards for the complete STN feature set, including the new numeric search feature. The Australian Patent Office is within the top 10 authorities concerning the number of patent applications over the past two decades. In the past years, over 20,000 applications were filed annually. A relatively large number of publications from the Australian Patent Office have their priority in Asian countries.

The records of the database contain bibliographic data, including patent applicant, inventor and legal representative information, patent, application and priority application data, IPC and EPC classification codes, abstract and the full-text of description and claims. Each database record contains all documents published for one application, displayed in order of appearance. Legal status data and family and citations display formats from the INPADOCDB database are available, as well as the searchable online thesauri for the International Patent Classification (/IPC) and European Patent Classification (/EPC and /ICO).

AUPATFULL is updated weekly.

STN Security - Be Protected

Security is on everyones mind these days. Here we present the first in a two part feature on how to make your STN sessions as secure as possible.

Secure Your Password

Regularly changing your password will ensure your STN account stays secure. Use the SET PASSWORD command, and use a password not easily guessed. 


  • 4 to 8 alphanumeric characters (longer is more secure)
  • two characters must differ from your current password
  • two characters not found in your STN login ID

If you use the auto-logon feature of STN Express, be sure to update your stored password when you change your STN password. 

  1. Select Setup from the main toolbar, select your STN setup and click Modify.
  2. Delete the contents of the Password field, enter your new password and then click OK. 
  3. When prompted, enter your new password again and click OK one more time.

Read part two next month as we continue STN Security with RSA Encryption and securing your session on STN on the Web and STN Easy. 

Examples of customer questions

Q. How can I refine my substance search using ring information?
A. You can use ring information to search REGISTRY for substances containing rings based on the number of rings, ring formula, etc. Ring Identifiers (/RID) are special dictionary terms, represented by a 3-part numeric sequence such as "2983.4.10". The first part "2983" codes the ring system arrangement; the second part "4" codes for ring atoms; and the third part 10 codes for the exact bonding pattern in the ring system.

If you know your RID, you can search REGISTRY using the corresponding numeric sequence followed by the "/RID" field code.

To locate the RID for a particular ring, you should first display a structure of interest and then enter "D RSD" at an arrow prompt for a structure of interest. You can use the first two groups of digits in the numeric sequence to identify substances with the same or similar ring system/atom arrangement.

Searching the full 3-part numeric sequence may be too limited, although it will find other substances in  REGISTRY with identical ring systems and the specific bonding pattern of the original substance.

Q: How can I display only the CAS Registry Number(R) and structure from CAS REGISTRYSM structure search within the coordinating CAplusSM records that have been indexed with a biological role indicator? 

A: Cross-over the L# from the REGISTRY structure search with the appropriate Role Code and display the CAplus records with the hitstr display format. Below is an example.
