The first part of the number,starting from the left, has 6 digits, 1,0,9,1,9 and 3 respectively; the second part has 2 digits, 0 and 7 respectively. Calculate Digit Verification of CAS Registry Number 109193-07: (8*1)+(7*0)+(6*9)+(5*1)+(4*9)+(3*3)+(2*0)+(1*7)=119 119 % 10 = 9 So 109193-07-9 is a valid CAS Registry Number.
