118968-66-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118968-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,6 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118968-66:
(8*1)+(7*1)+(6*8)+(5*9)+(4*6)+(3*8)+(2*6)+(1*6)=174
174 % 10 = 4
So 118968-66-4 is a valid CAS Registry Number.
