Check Digit Verification of cas no

The CAS Registry Mumber 189936-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,9,3 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 189936-33:
(8*1)+(7*8)+(6*9)+(5*9)+(4*3)+(3*6)+(2*3)+(1*3)=202
202 % 10 = 2
So 189936-33-2 is a valid CAS Registry Number.

Synthesis and reactions of a chemical model of the urocanase reaction

Winter, Joachim,Rétey, János

, p. 410 - 416 (1997)

Using a convergent synthetic strategy starting from nicotinic acid and imidazole, we have prepared the (E) and (Z) isomers of 1-benzyl-3-carbamoyl-5-[2-(ethoxycarbonylmethylene)-2(1-(p-tolylsulfamoyl)i midazol-4-yl)ethyl]pyridinium bromide (21) as models
