The CAS Registry Mumber 2841-28-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,4 and 1 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2841-28: (6*2)+(5*8)+(4*4)+(3*1)+(2*2)+(1*8)=83 83 % 10 = 3 So 2841-28-3 is a valid CAS Registry Number.
