253-88-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 253-88-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 253-88:
(5*2)+(4*5)+(3*3)+(2*8)+(1*8)=63
63 % 10 = 3
So 253-88-3 is a valid CAS Registry Number.
