Check Digit Verification of cas no
The CAS Registry Mumber 91871-12-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,7 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91871-12:
(7*9)+(6*1)+(5*8)+(4*7)+(3*1)+(2*1)+(1*2)=144
144 % 10 = 4
So 91871-12-4 is a valid CAS Registry Number.
