74459-08-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74459-08-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,5 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74459-08:
(7*7)+(6*4)+(5*4)+(4*5)+(3*9)+(2*0)+(1*8)=148
148 % 10 = 8
So 74459-08-8 is a valid CAS Registry Number.
