The CAS Registry Mumber 4184-44-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 4 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 4184-44: (6*4)+(5*1)+(4*8)+(3*4)+(2*4)+(1*4)=85 85 % 10 = 5 So 4184-44-5 is a valid CAS Registry Number.
