The CAS Registry Mumber 36931-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,9,3 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 36931-79:
(7*3)+(6*6)+(5*9)+(4*3)+(3*1)+(2*7)+(1*9)=140
140 % 10 = 0
So 36931-79-0 is a valid CAS Registry Number.
