The CAS Registry Mumber 2443-74-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,4 and 3 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2443-74: (6*2)+(5*4)+(4*4)+(3*3)+(2*7)+(1*4)=75 75 % 10 = 5 So 2443-74-5 is a valid CAS Registry Number.
