The CAS Registry Mumber 2133-10-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 3 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 2133-10: (6*2)+(5*1)+(4*3)+(3*3)+(2*1)+(1*0)=40 40 % 10 = 0 So 2133-10-0 is a valid CAS Registry Number.
