The CAS Registry Mumber 74996-52-4 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 2 respectively. Calculate Digit Verification of CAS Registry Number 74996-52: (7*7)+(6*4)+(5*9)+(4*9)+(3*6)+(2*5)+(1*2)=184 184 % 10 = 4 So 74996-52-4 is a valid CAS Registry Number.
