Check Digit Verification of cas no
The CAS Registry Mumber 12222-79-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12222-79:
(7*1)+(6*2)+(5*2)+(4*2)+(3*2)+(2*7)+(1*9)=66
66 % 10 = 6
So 12222-79-6 is a valid CAS Registry Number.
