Check Digit Verification of cas no
The CAS Registry Mumber 76231-79-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,3 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76231-79:
(7*7)+(6*6)+(5*2)+(4*3)+(3*1)+(2*7)+(1*9)=133
133 % 10 = 3
So 76231-79-3 is a valid CAS Registry Number.
