Check Digit Verification of cas no

The CAS Registry Mumber 72721-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,2 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72721-56:
(7*7)+(6*2)+(5*7)+(4*2)+(3*1)+(2*5)+(1*6)=123
123 % 10 = 3
So 72721-56-3 is a valid CAS Registry Number.

[Omim][Bf4] ionic liquid, a green and recyclable medium for one-pot aminomethylation of electron-rich aromatic compounds

Arzephoni, Amene Yaghoubi,Naimi-Jamal, M. Reza,Sharifi, Ali,Abaee, M. Saeed,Mirzaei, Mojtaba

, p. 216 - 218 (2013/07/05)

An efficient catalyst-free procedure has been developed for one-pot aminomethylation of some electron-rich aromatic compounds such as 1- and 2-naphthols, indole, N-methylindol and benzamide, in [omim][BF4] ionic liquid at room temperature. The ionic liquid can be recovered and reused without any noticeable loss of performance.
