InChIKey

The IUPAC International Chemical Identifier (InChI, see MIR:00000383) is an identifier for chemical substances, and is derived solely from a structural representation of that substance. Since these can be quite unwieldly, particularly for web use, the InChIKey was developed. These are of a fixed length (25 character) and were created as a condensed, more web friendly, digital representation of the InChI.

国际纯粹与应用化学联合会（IUPAC）国际化学物质标识符（InChI，参见MIR:00000383）是化学物质的标识符，它仅由该物质的分子结构表示形式衍生而来。鉴于这些标识符可能相当冗长，尤其在网络使用时，因此开发了InChIKey。这些标识符具有固定的长度（25个字符），并被设计为InChI的浓缩、更易于网络使用的数字表示形式。
