626-25-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 626-25-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 626-25:
(5*6)+(4*2)+(3*6)+(2*2)+(1*5)=65
65 % 10 = 5
So 626-25-5 is a valid CAS Registry Number.
