81741-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81741-83-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,4 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81741-83:
(7*8)+(6*1)+(5*7)+(4*4)+(3*1)+(2*8)+(1*3)=135
135 % 10 = 5
So 81741-83-5 is a valid CAS Registry Number.
