Check Digit Verification of cas no

The CAS Registry Mumber 124949-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,9,4 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 124949-26:
(8*1)+(7*2)+(6*4)+(5*9)+(4*4)+(3*9)+(2*2)+(1*6)=144
144 % 10 = 4
So 124949-26-4 is a valid CAS Registry Number.

A New Convenient Method for the Synthesis of Symmetrical and Unsymmetrical N,N'-Disubstituted Ureas

Izdebski, Jan,Pawlak, Danuta

, p. 423 - 425 (2007/10/02)

A new method is described for the preparation of symmetrically and unsymmetrically disubstituted ureas by aminolysis of bis(4-nitrophenyl) carbonate.The second substitution is slower than the first one, and it is possible to isolate monosubstituted intermediates when equimolar amounts of substrates are used.The reaction of the intermediates with different amines give unsymmetrical derivatives of urea.
