Check Digit Verification of cas no

The CAS Registry Mumber 1202783-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,7,8 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1202783-41:
(9*1)+(8*2)+(7*0)+(6*2)+(5*7)+(4*8)+(3*3)+(2*4)+(1*1)=122
122 % 10 = 2
So 1202783-41-2 is a valid CAS Registry Number.

Facile N-formylation of amines using Lewis acids as novel catalysts

Chandra Shekhar,Ravi Kumar,Sathaiah,Luke Paul,Sridhar, Madabhushi,Shanthan Rao

, p. 7099 - 7101 (2009)

Alky, aryl, and heteroaryl amines were found to react efficiently with formic acid under Lewis acid catalysis giving N-formyl derivatives in high yields. A study of ZnCl2-catalyzed N-formylation of a variety of amines using formic acid as formylating agent is described.
