Check Digit Verification of cas no
The CAS Registry Mumber 81968-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,6 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.Calculate Digit Verification of CAS Registry Number 81968-66:
(7*8)+(6*1)+(5*9)+(4*6)+(3*8)+(2*6)+(1*6)=173
173 % 10 = 3
So 81968-66-3 is a valid CAS Registry Number.
