CAS Announces Chemical Nomenclature Changes in CAS Databases. Revisions Will Make Chemical Names More Intuitive, Consistent. -------------------------------------------------------------------------------- Columbus, OH, November 28, 2006 - Starting in mid-December 2006, users of CAS databases will find significant changes in chemical substance nomenclature, Chemical Abstracts Service (CAS), a division of the American Chemical Society, announced during the Online Information 2006 conference held this week in London. Departing from its traditional practice of changing nomenclature at the end of 5-year collective index periods, CAS now implements changes in CAS nomenclature as appropriate to ensure the CAS RegistrySM has the most current, usable information. "The enhancements make the CASM index names more consistent and easier to understand," said CAS Vice President, Editorial Operations, Dr. Matthew J. Toussant. "The results are names that conform more closely with the substance names chemists typically use." Among the nomenclature improvements to be implemented are more uniformly cited locants, reduction in the number of stereoparent names, and the elimination of nearly 3,000 obscure stereoparents. Unexpressed amides also will be disregarded. Chemical names produced through the new system will begin to appear in CAS Registry database records in December. Old CA index names will be converted to the new nomenclature in 2007, but the old names will also be displayed in the Registry records. Chemical substance records containing CA index names, other chemical names, CAS Registry Number® identifiers, structures and other substance information are found in the CAS Registry, which is accessible through STN® and SciFinder® services. CAS, a division of the American Chemical Society, provides the world's largest and most current collection of chemical and related scientific information, including the most authoritative database of chemical substances, the CAS RegistrySM. CAS combines these databases with advanced search and analysis technologies to deliver the most complete, crosslinked and effective digital information environment for scientific research and discovery, including such products as SciFinder®, SciFinder Scholar™, STN®, STN Express® and STN AnaVist™, among others. The CAS web site is at www.cas.org. |
