The CAS Registry Mumber 198-08-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,9 and 8 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 198-08: (5*1)+(4*9)+(3*8)+(2*0)+(1*8)=73 73 % 10 = 3 So 198-08-3 is a valid CAS Registry Number.
