198895-89-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 198895-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,8,9 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 198895-89:
(8*1)+(7*9)+(6*8)+(5*8)+(4*9)+(3*5)+(2*8)+(1*9)=235
235 % 10 = 5
So 198895-89-5 is a valid CAS Registry Number.
