881198-66-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 881198-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,1,9 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 881198-66:
(8*8)+(7*8)+(6*1)+(5*1)+(4*9)+(3*8)+(2*6)+(1*6)=209
209 % 10 = 9
So 881198-66-9 is a valid CAS Registry Number.
