Stereochemical Chemical Abstracts Service

A general method of stereochemical notation based on the ligand priority sequence rule of Cahn, Ingold, and Prelog (CIP),8,9 developed at Chemical Abstracts Service,0 1 has been in use in Chemical Abstracts Chemical Substance Indexes for mononuclear coordination compounds since 1972. [Pg.128]

Carbohydrate nomenclature impacts on stereochemistry, and on the nomenclature of compounds other than mainstream carbohydrates (e.g., hydroxylactones), often named as modihed carbohydrates in Chemical Abstracts Service (CAS) and elsewhere. For further stereochemical information on carbohydrates, see Chapter 7. [Pg.81]

Conforming to these principles, Chemical Abstracts Service has devised a stereochemical notation which was first introduced into the Chemical Abstracts Service Chemical Registry. System and CA Indexes in 1972 (7) and was extended to higher coordination numbers in 1977 (8). [Pg.406]

CAS = Chemical Abstracts Service CT = connection table HTSS = hierarchical tree substructure search lO = input-output RDBMS = relational database management system SEMA = stereochemically extended Morgan algorithm. [Pg.2764]
