The CAS Registry Mumber 933-71-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 3 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 933-71: (5*9)+(4*3)+(3*3)+(2*7)+(1*1)=81 81 % 10 = 1 So 933-71-1 is a valid CAS Registry Number.
