The CAS Registry Mumber 74118-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,1 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74118-03:
(7*7)+(6*4)+(5*1)+(4*1)+(3*8)+(2*0)+(1*3)=109
109 % 10 = 9
So 74118-03-9 is a valid CAS Registry Number.
