The CAS Registry Mumber 813-42-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 3 respectively; the second part has 2 digits, 4 and 2 respectively. Calculate Digit Verification of CAS Registry Number 813-42: (5*8)+(4*1)+(3*3)+(2*4)+(1*2)=63 63 % 10 = 3 So 813-42-3 is a valid CAS Registry Number.
