CHEMICAL STRUCTURAL SUBDATABASE AND PATTERN OUTPUT SUBSYSTEM
化学物质结构信息系统的建立及图形输出子系统

The structural subdatabase and the pattern output subsystem of the Database "of Toxicity of Chemical Compounds are presented. All system utility software, including creating, retrieval and pattern output, were written in high-level language. CAS Registry Number is made as an access key. the structural topological codes of compounds are directly accessible. The system can be used in searching of the structures of chemicals.
