Moreover, CambridgeSoft provides a database of 2,500 micromolecules which can be searched at no cost with their utility ChemFinder, from the web.
The resulting structure files can be displayed by ChemDraw or Chem3D, but are in a proprietary format which can't be displayed by RasMol. However, with the free version of ChemDraw, you can convert a ChemFinder structure to SMILES format. You can then submit the SMILES formula to CORINA, which will return a PDB file viewable in RasMol.
