Chemical Abstracts Service (CAS), a division of the American Chemical Society, has announced that it recently recorded the 50 millionth substance in CAS REGISTRY. The CAS REGISTRY claims to be the most comprehensive and high-quality compendium of publicly disclosed chemical information. This milestone comes only 9 months after CAS registered its 40 millionth substance. The recently registered substance is a novel arylmethylidene heterocycle with analgesic properties.
REGISTRY is the only integrated comprehensive source of chemical information from a full range of patent and journal literature that is curated and quality controlled by scientists working around the world. For more than 100 years, CAS scientists and colleagues in several nations have meticulously analysed and indexed publicly disclosed global scientific information to build up the unique REGISTRY resource that provides not only chemical names, the unique CAS Registry Number, and vital literature references but also ancillary information such as experimental and predicted property data (boiling and melting points, etc.), commercial availability, preparation details, spectra, and regulatory information from international sources.
The 50 millionth substance (CAS Registry Number 1181081-51-5) was uncovered by CAS scientists from the Examples section of a nearly 200-page patent issued by the World Intellectual Property Organization on August 13, 2009. According to the patent, "Few therapeutics are approved by the US Food and Drug Administration and other regulatory agencies for the treatment of neuropathic pain." To address this concern, a series of novel arylmethylidene heterocycles were synthesized, which included the most recent substance registered by CAS.
CAS REGISTRY is available to scientists through CAS' SciFinder, and its STN family of products. With these advanced search and analysis technologies, CAS helps scientists find reliable information that is vital to their research process.
