The first part of the number,starting from the left, has 5 digits, 7,5,0,1 and 9 respectively; the second part has 2 digits, 0 and 6 respectively. Calculate Digit Verification of CAS Registry Number 75019-06: (7*7)+(6*5)+(5*0)+(4*1)+(3*9)+(2*0)+(1*6)=116 116 % 10 = 6 So 75019-06-6 is a valid CAS Registry Number.
