539-71-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 539-71-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 539-71:
(5*5)+(4*3)+(3*9)+(2*7)+(1*1)=79
79 % 10 = 9
So 539-71-9 is a valid CAS Registry Number.
