A few comments. To check the pdf against scifinder as-is (for someone using only one monitor/laptop screen) requires a lot of alt-tab window switching. Copying individual CAS numbers from the PDF into the Scifinder window (which can accept a text file or multiple lines) is not very efficient.
Visit the authority for CAS numbers and use either Scifinder or STN to search/validate the CAS number for the represented structure. There ARE multiple CAS numbers associated with a single compound so the CAS number itself might need to be annotated.
This is very strange, it is trans,trans in the union file and cis,cis in the wikichem file (I have been using the union file to verify CAS numbers). I need to look into this. Ambix 12:47, 12 February 2009 (UTC) Glucose 1-phosphate One chiral center is not specified (should be up to match CAS). (probably a result of copying glucose skeleton, in ...
According to CAS, his visionary view of CAS' potential "led to expansion, modernization, and the forging of international alliances with other information organizations." [15] CAS was an early leader in the use of computer technology to organize and disseminate information. [16] The CAS Chemical Registry System was introduced in 1965.
Many of these database companies use the same name for their file format as they do for their database (including Copac, CSA, ISI, Medline, Ovid, PubMed, and SciFinder). For the ability to retrieve citations from the particular databases (rather than the file format), please refer to the database connectivity table that is below this table.
A Texas woman is charged with murder after police say she fatally shot her husband, lit his truck on fire and fled the scene in a kayak. Bexar County, Texas officials found the body of Tomas ...
Some registration systems such as the CAS system make use of algorithms to generate unique hash codes to achieve the same objective. A key difference between a registration system and a simple chemical database is the ability to accurately represent that which is known, unknown, and partially known.
