Cactus Tools (2)
resolve
NCI CACTUS chemical identifier resolver. Convert one chemical identifier (a drug/chemical name, CAS number, SMILES, InChI, or InChIKey) into a single representation: smiles (canonical SMILES), stdinchi (standard InChI), stdinchikey (standard InChIKey), iupac_name, names (synonym list), formula (mol…
identify
NCI CACTUS one-shot lookup: given any chemical identifier (name, CAS, SMILES, InChI, or InChIKey), return SMILES, InChIKey, IUPAC name, molecular formula, molecular weight, and CAS number in a single call. Fields that cannot be resolved are returned as null. Keyless, plain-text API.
