The CAS Registry Mumber 72740-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 72740-33: (7*7)+(6*2)+(5*7)+(4*4)+(3*0)+(2*3)+(1*3)=121 121 % 10 = 1 So 72740-33-1 is a valid CAS Registry Number.
