This limits its usefulness for substructure search or display of stereochemistry in the structure diagram. CAS is currently preparing to augment the Registry connection table with atom/b

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
