The CAS Registry Mumber 499798-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,7,9 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 499798-19:
(8*4)+(7*9)+(6*9)+(5*7)+(4*9)+(3*8)+(2*1)+(1*9)=255
255 % 10 = 5
So 499798-19-5 is a valid CAS Registry Number.
