Check Digit Verification of cas no
The CAS Registry Mumber 12221-89-5 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 1 respectively; the second part has 2 digits, 8 and 9 respectively.Calculate Digit Verification of CAS Registry Number 12221-89:
(7*1)+(6*2)+(5*2)+(4*2)+(3*1)+(2*8)+(1*9)=65
65 % 10 = 5
So 12221-89-5 is a valid CAS Registry Number.
