Check Digit Verification of cas no
The CAS Registry Mumber 71936-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,3 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71936-81:
(7*7)+(6*1)+(5*9)+(4*3)+(3*6)+(2*8)+(1*1)=147
147 % 10 = 7
So 71936-81-7 is a valid CAS Registry Number.
