Can be used in to type a SMILES/InChI/CAS number of which the structure is to be drawn.
The SMILES is parsed by CDK's smiles.SmilesParser class and layout into a 2D structure using the layout.StructureDiagramGenerator.
The CAS number is looked up in the pubchem database. You need to be online to have this working. If the CAS is not in PubChem, it will not work.
The InChI is read via the InChI implementation form IUPAC. This is a C++ code, which must be installed separately (see http://sourceforge.net/projects/jni-inchi). Layout is again done via CDK's StructureDiagramGenerator.
