Check which molecules vendors list as in stock before docking or making them. Each molecule is matched by InChIKey against a pinned snapshot of the ZINC20 in-stock catalogs, first as drawn, then as its neutral parent (salt and protonation forms), then by connectivity (any stereoisomer), and the strongest match names the ZINC substance, its vendors and their catalog numbers. The in-stock molecules come out as a set ready for enumeration, filtering or docking.

Molecules
Paste SMILES or InChI one per line, or mol blocks / SDF records. At most 10,000 molecules. Salts and charged forms are fine: each molecule is also matched by its neutral parent.

Matching
In stock means listed as in stock by a ZINC20 vendor catalog when the snapshot was taken. Stock changes, and ZINC publishes no prices or lead times, so confirm with the vendor before ordering.
Same parent after dropping common counterions and solvents, keeping the largest fragment and neutralizing charges, so salts and protonation states of the compound count. Stereochemistry must match.
In-stock listings from ZINC20 (Irwin et al., J. Chem. Inf. Model. 2020). Matching runs on a local snapshot; no structure is sent to ZINC or to a vendor.
