Check Digit Verification of cas no

The CAS Registry Mumber 1602636-82-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,2,6,3 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1602636-82:
(9*1)+(8*6)+(7*0)+(6*2)+(5*6)+(4*3)+(3*6)+(2*8)+(1*2)=147
147 % 10 = 7
So 1602636-82-7 is a valid CAS Registry Number.

Facile synthesis of 1,2,4-trisubstituted imidazoles via aerobic copper catalyzed ligand-free [3+2] cycloaddition

Li, Wei,Tian, Weixiang Jiao Wan,Lei, Ming

, p. 386 - 392 (2014/05/20)

A simple and facile approach to highly functionalized imidazole derivatives in moderate to good yields has been developed. This method involves copper catalyzed aerobic [3+2] cycloaddition of amidines with nitroolefins in absence of ligand. Based on observation of the intermediates, possible reaction mechanism different from the same reported approach was proposed.
