480-52-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 480-52-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,8 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 480-52:
(5*4)+(4*8)+(3*0)+(2*5)+(1*2)=64
64 % 10 = 4
So 480-52-4 is a valid CAS Registry Number.
