The CAS Registry Mumber 1133-40-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1133-40: (6*1)+(5*1)+(4*3)+(3*3)+(2*4)+(1*0)=40 40 % 10 = 0 So 1133-40-0 is a valid CAS Registry Number.
