The CAS Registry Mumber 2224-66-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,2 and 4 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2224-66: (6*2)+(5*2)+(4*2)+(3*4)+(2*6)+(1*6)=60 60 % 10 = 0 So 2224-66-0 is a valid CAS Registry Number.
