Template:CAS
CAS registry numbers are unique numerical identifiers for chemical elements, compounds, polymers, biological sequences, mixtures and alloys. They are also referred to as CAS numbers, CAS RNs or CAS #s. This template is used to cite CAS numbers within articles.

If the first parameter contains a valid CAS-number bevat (e.g. no letters) a link will be placed to the "National Library of Medicine - Medical Subject Headings". If it is not a valid number, plain text will be shown. In any case, leading and ending spaces are trimmed. Text in the second parameter (if given) will be shown as plain text.
