A program (FORMULA) is described which translates the systematic chemical names of steroids to structural formulas which, with a suitable graphic output device could be used for direct typesetting. (10 references) (Author)

The computerized conversion of Wiswesser Line Notations to Ring Codes, using a two-part approach, and the set of computer programs generated for the conversion of ring systems are described. (9 references) (Author)

Analysis of the distribution of relevant answers to 41 search profiles among the 80 subject sections of Chemical Abstracts" revealed that the average profile requires 10 CA-subject sections for adequate coverage. The average printing expense could be reduced 25 percent by searching the individual profiles in the appropriate subject sections. (5…

A design is described for a system to manage the information directly related to the experimental work in a toxicological laboratory. A number of distinct input procedures provide data to a set of co-existing data bases. Periodic, event-triggered, predefined demand, and ad hoc reports are posited. (12 references) (Author/NH)

Among other improvements in chemical nomenclature used in the Chemical Registry System, Chemical Abstracts Service intends to standardize the fundamental principles for naming cyclic structures so that procedures for the derivation of ring names can become more amenable to computer generation and translation.
