The first part of the number,starting from the left, has 5 digits, 7,4,8,0 and 8 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 74808-14: (7*7)+(6*4)+(5*8)+(4*0)+(3*8)+(2*1)+(1*4)=143 143 % 10 = 3 So 74808-14-3 is a valid CAS Registry Number.
