Hello,
CAS numbers are used to identify chemical compounds [1]. Someone on fr.wp has created a template for CAS numbers; it uses the CAS number as a parameter and outputs some links to several resources/databases [2]. The thing is, although these links might be useful, the articles aren't really the good place for them.
I was wondering if someone from this list would be willing to write a simple tool on the toolserver à la GeoHack. The tool would do exactly what the template is doing right now, i.e. it would check the validity of the input and would output a few links [3]. The template would then be modified to simply link to this tool.
This should be pretty easy (I think) and it would avoid displaying all these links inside the articles. Anyone interested? Many thanks in advance.
