"Obtain quality 3D coordinates for your own chemical structures from the CORINA progam."[1]
"Enter a structure as SMILES string and an identifier in the form below and press the Submit button (or just use "alanin" for demonstration). CORINA will generate 3D coordinates for the given structure. A new page will be generated showing the 3D molecular model if you have RASMOL, CHIME, or some similar program installed on your computer). "[2]

"Substance Registry Services (SRS) is the Environmental Protection Agency's (EPA) central system for information about substances that are tracked or regulated by EPA or other sources. It is the authoritative resource for basic information about chemicals, biological organisms, and other substances of interest to EPA and its state and tribal partners.

The SRS makes it possible to identify which EPA data systems, environmental statutes, or other sources have information about a substance and which synonym is used by that system or statute. It becomes possible therefore to map substance data across EPA programs regardless of synonym.

The system provides a common basis for identification of, and information about:

• Chemicals
• Biological organisms
• Physical properties
• Miscellaneous objects"[1]
