Check Digit Verification of cas no

The CAS Registry Mumber 32903-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,9,0 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 32903-81:
(7*3)+(6*2)+(5*9)+(4*0)+(3*3)+(2*8)+(1*1)=104
104 % 10 = 4
So 32903-81-4 is a valid CAS Registry Number.

SELECTIVE NITROSATION OF POLYMETHYLENEBIS-(3-ALKYLUREAS)

Lutsenko, V. V.,Blyum, R. A.,Mikul'skene, G. V.,Mikul'skis, P. P.

, p. 1366 - 1371 (2007/10/02)

Nitrosation of ethylenebis-(3-hexylurea) and hexamethylenebis with sodium nitrite in acid solution gives the isomeric symmetrical NN- and N'N'-bisnitrosoureas and the nonsymmetrical NN'-dinitrosoureas.The regioisomers were separated by TLC, and their structures proved by 1H and 13C NMR spectroscopy.
