Check Digit Verification of cas no
The CAS Registry Mumber 14874-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,8,7 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 14874-82:
(7*1)+(6*4)+(5*8)+(4*7)+(3*4)+(2*8)+(1*2)=129
129 % 10 = 9
So 14874-82-9 is a valid CAS Registry Number.
