Check Digit Verification of cas no
The CAS Registry Mumber 74714-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,1 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74714-13:
(7*7)+(6*4)+(5*7)+(4*1)+(3*4)+(2*1)+(1*3)=129
129 % 10 = 9
So 74714-13-9 is a valid CAS Registry Number.
