Template documentation[view] [edit] [history] [purge]

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.

Usage

{{CAS|74-79-3|(L-arginine)<br/>157-06-2 (D-arginine)}}

If the first parameter contains a valid CAS-number bevat (e.g. no letters) a link will be placed to CAS number tool on the WikiMedia Toolserver. 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.

Example

157-06-2 (D-arginine) 74-79-3 (L-arginine)
157-06-2 (D-arginine)
