The CAS Registry Mumber 1149-66-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 9 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1149-66: (6*1)+(5*1)+(4*4)+(3*9)+(2*6)+(1*6)=72 72 % 10 = 2 So 1149-66-2 is a valid CAS Registry Number.
