CAS Content Enhancements
In Fall 2008, the Chemical Abstracts Service (CAS) databases were enhanced with content from Wiley reaction collections. These evaluated collections represent respected reference works, and inclusion of these reactions offer access to important older reaction information, along with links to Wiley InterScience full-text articles that describe these reactions in depth.
The first collection, Encyclopedia of Reagents for Organic Synthesis (EROS), began appearing in CA/CAplus and CASREACT in September 2008. EROS is considered the definitive reference source for reagents used in organic synthesis.
The addition of two other Wiley collections, Organic Syntheses and Organic Reactions, is planned for the near future. These collections will further enrich the CAS databases with older reactions, dating back to 1921.
Other content enhancements include:
- Records for U.S. patents now extend back to the first decade of the 19th century. In July 2008, CAS added more than 1,250 records for patents issued from 1808–1859.
- CAS is currently covering utility models from China, Japan, and South Korea; by the end of 2008, CAS will cover utility models from the beginning of 2006 to the present for all three countries.
- Additional records for documents published in The Royal Society of Chemistry (RSC) journals from 1878–1889 were loaded to Volume 0/1906 of CA/CAplus.
- More than 200 million citations are accessible in CA/CAplus.
- Through the end of July, nearly 671,000 exemplified prophetic substances from more than 2,500 core patents published in English, French, German, and Japanese were added to CAS databases.
- Beginning in July 2008, the Patent Cooperation Treaty (PCT) applications and their national equivalents from France, Germany, U.S., Canada, Great Britain, and EPO are both covered and indexed as basics.
- CHEMCATS® now contains more than 23 million commercially available chemicals.
- CAS expands collection of experimental and predicted physical properties in the CAS REGISTRY database to total 1.7 billion predicted properties and a total of 10.1 million experimental spectra, property values, and data tags.
