The CAS lookup link at NIST does not seem to work; either the CAS numbers are wrong or NIST does not have it in its database.
[edit] Cas numbers
I made a search on Beilstein with a structural search. The compound was known as "MalachitGruen" with CAS number: 10309-95-2. However, the compound was not on the CAS database either. I removed the external links because they were broken and no longer relevant. The naming system of the forms of malachite green was based on the journal articles in the sources.
[edit] IUPAC name
The IUPAC name quoted in the existing article doesn't make sense as stated because it doesn't account for the methylene moiety, so I checked on it. According to the Merck Index, the correct Chemical Abstracts Service (CAS)name for malachite green, which seems more logical to me, is:
N-[4-[[4-(Dimethylamino)-phenyl]phenylmethylene]-2,5-cyclohexadien-1-ylidene]-N-methylmethanaminium chloride
Merck also list the CAS number as: [569-64-2], which confirms that shown in the article.
