Check Digit Verification of cas no
The CAS Registry Mumber 12226-38-9 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 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12226-38:
(7*1)+(6*2)+(5*2)+(4*2)+(3*6)+(2*3)+(1*8)=69
69 % 10 = 9
So 12226-38-9 is a valid CAS Registry Number.
