Relative Configurations in Stereochemical Substructure Search,tereochemical search capability could be implemented by extending the present search system to determine the stereochemical validity of a topological substructure match. However, much of the stereochemistry in the Registry is described only in terms of relative configurations. When relative stereoch

The Du Pont Global Technical Information System,amed SCION, consists of a chemical file and a document file. A unique feature of this system is that both Du Pont proprietary files and publicly available files on STN International can be searched using the same MESSENGER command language. The chemical file contains structures, Du Pont accession nu

Finding those rings necessary and sufficient for unambiguous representation, in an efficient manner and for the worst cases is not trivial. Issues include the 2-D representation of 3-D structures, the definition and perception of a ring set, and whether vertex
