Check Digit Verification of cas no
The CAS Registry Mumber 71832-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,3 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71832-81:
(7*7)+(6*1)+(5*8)+(4*3)+(3*2)+(2*8)+(1*1)=130
130 % 10 = 0
So 71832-81-0 is a valid CAS Registry Number.
