28668-19-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28668-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,6 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28668-19:
(7*2)+(6*8)+(5*6)+(4*6)+(3*8)+(2*1)+(1*9)=151
151 % 10 = 1
So 28668-19-1 is a valid CAS Registry Number.
