CACHE is "Critical Assessment of Computational Hit-finding Experiments". The plan for CACHE is outlined in an article now available at Nature Reviews Chemistry. https://www.nature.com/articles/s41570-022-00363-z
You are also welcome to screen the Enamine library direct from Enamine (below). ZINC is provided in the hope that it will be useful, but you must use it at your own risk.

---|---|---|---|---|
In-stock | 3M-4M | 3D, 1 GB per million molecules in sdf and pdbqt formats. slightly more, 1.6 GB per million in mol2. 40 GB per million in db2 | ZINC20 | Select 3D, purchasability level: "agent", meaning compounds that are on the shelf somewhere and available direct from suppliers or procurement agents (e.g. Molport, eMolecules). About 90% expected sourcing success rate. |

Because of the war in Eastern Europe, we are making available additional libraries that may be easier to access because the stocks are not held in a war zone. We include the original smiles, plus we have calculated InChIkey and the ZINC-22 tranche, which includes the heavy atom count and logP bin.
