Check Digit Verification of cas no
The CAS Registry Mumber 12217-22-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,1 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 12217-22:
(7*1)+(6*2)+(5*2)+(4*1)+(3*7)+(2*2)+(1*2)=60
60 % 10 = 0
So 12217-22-0 is a valid CAS Registry Number.
