82-31-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82-31-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82-31:
(4*8)+(3*2)+(2*3)+(1*1)=45
45 % 10 = 5
So 82-31-5 is a valid CAS Registry Number.
