The CAS Registry Mumber 4408-07-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 8 respectively; the second part has 2 digits, 0 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4408-07: (6*4)+(5*4)+(4*0)+(3*8)+(2*0)+(1*7)=75 75 % 10 = 5 So 4408-07-5 is a valid CAS Registry Number.
