The CAS Registry Mumber 119880-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,8 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119880-03:
(8*1)+(7*1)+(6*9)+(5*8)+(4*8)+(3*0)+(2*0)+(1*3)=144
144 % 10 = 4
So 119880-03-4 is a valid CAS Registry Number.
