Check Digit Verification of cas no
The CAS Registry Mumber 13389-88-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,8 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13389-88:
(7*1)+(6*3)+(5*3)+(4*8)+(3*9)+(2*8)+(1*8)=123
123 % 10 = 3
So 13389-88-3 is a valid CAS Registry Number.
