84985-45-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84985-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,8 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 84985-45:
(7*8)+(6*4)+(5*9)+(4*8)+(3*5)+(2*4)+(1*5)=185
185 % 10 = 5
So 84985-45-5 is a valid CAS Registry Number.
