Structure searching of the CAS 9 million plus files of connection tables costs about $ - per hour. The current cost of the Beilstein Online factual and structure files averages to $ - per hour for both STN and DIALOG, although the cost can go considerably higher, depending on the exact nature of what one does on the system. The digits before the first hyphen represent the CAS (Chemical Abstracts Service) and remaining digits denote the registry number. For example, in case of aspirin, the CAS number is Here 50 represents CAS and represents registry number. Some example chemical substance CAS registry numbers are: Aspirin: ; Water:   Use your existing chemical drawing programs (e.g., ChemDraw, ACD ChemSketch, Marvin Sketch) to generate a computer-readable SMILES formula for each compound presented in your article.

Based on nomenclature used in the eighth collective index to Chemical abstracts, [] American Chemical Society. Development of the computer-readable version of the Beilstein database prompted an extended review of factual and substructure search techniques.

In order to provide appropriate access to the three-dimensional structure information in combination with the extensive range of physical property information, new methods of online access had to be Author: Peter F. Rusch.

By earlythe CAS Registry, no longer experimental, began to include all chemical substances indexed in Chemical Abstracts, with their structures and names recorded in computer-readable files.

Every substance was given a permanent, unambiguous and unique identifying number, the CAS. The increasing availability of computer-readable files of chemical nomenclature and of programs for text searching has led to the development of methods for performing substructure searches in.

A CAS Registry Number, also referred to as CASRN or CAS Number, is a unique numerical identifier assigned by the Chemical Abstracts Service (CAS) to every chemical substance described in the open scientific literature (currently including all substances described from through the present, plus some substances from the early or mid s), including organic and inorganic compounds.
