Check Digit Verification of cas no
The CAS Registry Mumber 12220-06-3 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 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 12220-06:
(7*1)+(6*2)+(5*2)+(4*2)+(3*0)+(2*0)+(1*6)=43
43 % 10 = 3
So 12220-06-3 is a valid CAS Registry Number.
