Check Digit Verification of cas no

The CAS Registry Mumber 667422-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,7,4,2 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 667422-06:
(8*6)+(7*6)+(6*7)+(5*4)+(4*2)+(3*2)+(2*0)+(1*6)=172
172 % 10 = 2
So 667422-06-2 is a valid CAS Registry Number.

Copper(I)-Catalyzed regioselective amination of N -aryl imines using TMSN3 and TBHP: A route to substituted benzimidazoles

Mahesh, Devulapally,Sadhu, Pradeep,Punniyamurthy, Tharmalingam

, p. 1644 - 1650 (2015/02/19)

A novel and efficient copper-catalyzed amination of N-aryl imines is described. This one-pot, multicomponent reaction, in which imine acts as a directing group by chelating to the metal center, affords a potential route for the transformation of the commercial aryl amines, aldehydes, and azides into valuable benzimidazole structural units with wide substrate scope and diversity. The synthetic and mechanistic aspects are presented.
