913728-83-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 913728-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,3,7,2 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 913728-83:
(8*9)+(7*1)+(6*3)+(5*7)+(4*2)+(3*8)+(2*8)+(1*3)=183
183 % 10 = 3
So 913728-83-3 is a valid CAS Registry Number.
