83983-71-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83983-71-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,8 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83983-71:
(7*8)+(6*3)+(5*9)+(4*8)+(3*3)+(2*7)+(1*1)=175
175 % 10 = 5
So 83983-71-5 is a valid CAS Registry Number.
