52-44-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52-44-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52-44:
(4*5)+(3*2)+(2*4)+(1*4)=38
38 % 10 = 8
So 52-44-8 is a valid CAS Registry Number.
