89537-65-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89537-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,3 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89537-65:
(7*8)+(6*9)+(5*5)+(4*3)+(3*7)+(2*6)+(1*5)=185
185 % 10 = 5
So 89537-65-5 is a valid CAS Registry Number.
