Structure and nomenclature search system

Structure and Nomenclature Search System. This system links the collection of chemical databases found in the Chemical Information System (CIS), one of the first interactive systems for stmcture and substmcture searching. References from the separate files can be retrieved by SANSS using CAS Registry Numbers, and the database of stmctures may be searched for stmctures or substmctures. An adaptation of the SANSS software for substmcture searching has been incorporated in the Dmg Information System of the National Cancer Institute for its own use (54).

NRC/U.S. Coast Guard coordinate numerous information services, systems, and centers to assist in emergency response. Included are the Marine Safety Information Center, Hazard Assessment Control System, Chemical Hazard Response Information System, Oil and Hazardous Materials-Technical Assistance Data System, Structural and Nomenclature Search System, and Pollution Equipment Inventory System. 

All atoms were drawn with whatever atom symbol had last been selected. To select an atom symbol the user touched the LABEL ATOM menu item, which caused a secondary menu of atom symbols to appear at the bottom of the screen in the message area previously reserved. The list was chosen by frequency of appearance in organic compounds as determined by an examination of compounds in the Structure and Nomenclature Search System (a component of The Chemical Information System). Similarly, bonds were drawn using the last selected bond type. 

The Registry of Toxic Effects of Chemical Substances (RTECS) is published annually by the US National Institute for Occupational Safety and Health (Ohio). The computerized version, which contains data on over 40000 compounds, is available via the TOXLINE system of the US National Library of Medicine and the Chemical Information Service (CIS), sponsored jointly by the National Institutes of Health and the Environmental Protection Agency, Washington. Within CIS there exists also a powerful structural search system known as SANSS (Structure and Nomenclature Search System) which provides... 

The earliest system which allowed substructure searching involving chemical connectivity input and structure display, was the National Institutes of Health/ Environmental Protection Agency Chemical Information System, the NIH/EPA CIS 14). Its Structure and Nomenclature Search System (SANSS) eventually allowed access to a large range of public data bases. The system allowed access from teletype terminals and was not graphics-based.
