Check Digit Verification of cas no
The CAS Registry Mumber 74209-35-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,0 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74209-35:
(7*7)+(6*4)+(5*2)+(4*0)+(3*9)+(2*3)+(1*5)=121
121 % 10 = 1
So 74209-35-1 is a valid CAS Registry Number.

A new class of 7-aminohaloindazoles has been synthesized. Reactivity of the amino groups of these bicyclic systems has been investigated. The halogenated pyrazolo-1,5-benzodiazepinones have been synthesized by the condensation of 7-aminoindazoles with ethyl acetoacetate.
