Check Digit Verification of cas no

The CAS Registry Mumber 1054616-53-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,4,6,1 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1054616-53:
(9*1)+(8*0)+(7*5)+(6*4)+(5*6)+(4*1)+(3*6)+(2*5)+(1*3)=133
133 % 10 = 3
So 1054616-53-3 is a valid CAS Registry Number.

A simple conversion of amines into monosubstituted ureas in organic and aqueous solvents

Liu, Qi,Luedtke, Nathan W.,Tor, Yitzhak

, p. 1445 - 1447 (2001)

A versatile and highly efficient synthesis of monosubstituted ureas is described. The reaction of an amine with 4-nitrophenyl-N-benzylcarbamate, followed by hydrogenolysis, provides the corresponding urea in high yield and purity. This carbamate can also be employed for the derivatization of water-soluble polyamines (e.g. aminoglycoside antibiotics), while other reagents (e.g. benzylisocyanate) fail to give the desired products in any significant yield.
