The CAS Registry Mumber 1818-09-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,1 and 8 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1818-09: (6*1)+(5*8)+(4*1)+(3*8)+(2*0)+(1*9)=83 83 % 10 = 3 So 1818-09-3 is a valid CAS Registry Number.
