The first part of the number,starting from the left, has 5 digits, 8,0,3,8 and 4 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 80384-26: (7*8)+(6*0)+(5*3)+(4*8)+(3*4)+(2*2)+(1*6)=125 125 % 10 = 5 So 80384-26-5 is a valid CAS Registry Number.
