The CAS Registry Mumber 1448-82-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,4 and 8 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1448-82: (6*1)+(5*4)+(4*4)+(3*8)+(2*8)+(1*2)=84 84 % 10 = 4 So 1448-82-4 is a valid CAS Registry Number.
