SMILES exercises: Molecule → SMILES — smiles.cheminfo.org

SMILES exercises: Molecule → SMILESA structure is drawn for you; write the SMILES. Any correct SMILES is accepted — what is compared is the molecule, never the string.Convert between chemical structures and SMILES in both directions, search a list of structures by substructure or SMARTS, and learn the notation step by step. Everything runs in your browser — no structure you open ever leaves your machine — so the tool needs JavaScript.

Converter — draw a structure, read its SMILES

Lists — convert and search a whole set

Tutorial — the notation, one step at a time

Exercises — write it and be marked on it

SMILES sheet — every construct of the notation

SMARTS sheet — every primitive of the query language

The OpenSMILES specification

About — what the tool runs on, and how to cite it
