81635-54-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81635-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,3 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81635-54:
(7*8)+(6*1)+(5*6)+(4*3)+(3*5)+(2*5)+(1*4)=133
133 % 10 = 3
So 81635-54-3 is a valid CAS Registry Number.
