    Variable resolveEnglishChemicalConst

    resolveEnglishChemical: (term: string) => Promise<EnglishChemical | undefined> = ...

    Resolves a chemical name written in English or a configured source language (see wikidata.sourceLanguages in config.json, e.g. Dutch zoutzuur) to its English name and CAS number. The term must equal a Wikidata label or alias exactly, so an unrelated top search hit is never trusted. Cached for wikidata.ttlDays; a definitive "no match" is cached as {}, a failed request (undefined) is not.

    Type declaration

      • (term: string): Promise<EnglishChemical | undefined>

      • Parameters

        • term: string

          A chemical name, e.g. zoutzuur or acetone

        Returns Promise<EnglishChemical | undefined>

        The English name and CAS, {} when nothing matches, or undefined if the lookup failed

    await resolveEnglishChemical("zoutzuur");
    // Returns: { name: "hydrochloric acid", cas: "7647-01-0" }
    await resolveEnglishChemical("not a chemical");
    // Returns: {}
