97589-53-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97589-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,8 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 97589-53:
(7*9)+(6*7)+(5*5)+(4*8)+(3*9)+(2*5)+(1*3)=202
202 % 10 = 2
So 97589-53-2 is a valid CAS Registry Number.
