Check Digit Verification of cas no

The CAS Registry Mumber 1313395-60-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,3,9 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1313395-60:
(9*1)+(8*3)+(7*1)+(6*3)+(5*3)+(4*9)+(3*5)+(2*6)+(1*0)=136
136 % 10 = 6
So 1313395-60-6 is a valid CAS Registry Number.

A rapid and simple amine-catalyzed microwave-assisted isomerization of maleamides into fumaramides

Majce, Vita,Ko?evar, Marijan,Polanc, Slovenko

, p. 3287 - 3290 (2011)

An improved, efficient, and simple method for the synthesis of nonsymmetrical diamides of fumaric acid is reported. Starting from commercially available substrates, maleic diamides are formed in two steps, and then isomerized in a focused microwave reactor in acetonitrile as the solvent in the presence of a catalytic amount of piperidine, giving the corresponding fumaramides in high yields and purity.
