Check Digit Verification of cas no

The CAS Registry Mumber 1249400-33-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,9,4,0 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1249400-33:
(9*1)+(8*2)+(7*4)+(6*9)+(5*4)+(4*0)+(3*0)+(2*3)+(1*3)=136
136 % 10 = 6
So 1249400-33-6 is a valid CAS Registry Number.

A facile IL-DMSO assisted synthesis of 5-, 6-, and 7-membered benzo-annelated cyclic guanidines

Verma, Amit,Giridhar, Rajani,Modh, Pratik,Yadav, Mange Ram

supporting information; experimental part, p. 2954 - 2958 (2012/07/28)

A new and facile IL-DMSO assisted method has been developed for the synthesis of biologically important cyclic guanidines like 2-aminobenzimidazole, 2-imino-4-quinazolinone, and 2-imino-5-benzotriazepinones at ambient temperatures. The desired products could be obtained by microwave irradiation32 also, but at elevated temperatures. A plausible mechanism for catalysis has been proposed.
