The first part of the number,starting from the left, has 5 digits, 9,9,1,9 and 9 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 99199-03: (7*9)+(6*9)+(5*1)+(4*9)+(3*9)+(2*0)+(1*3)=188 188 % 10 = 8 So 99199-03-8 is a valid CAS Registry Number.
