The CAS Registry Mumber 74996-51-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,9 and 6 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 74996-51: (7*7)+(6*4)+(5*9)+(4*9)+(3*6)+(2*5)+(1*1)=183 183 % 10 = 3 So 74996-51-3 is a valid CAS Registry Number.
