28097-22-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28097-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,9 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 28097-22:
(7*2)+(6*8)+(5*0)+(4*9)+(3*7)+(2*2)+(1*2)=125
125 % 10 = 5
So 28097-22-5 is a valid CAS Registry Number.
