Uses
1H,1H,9H-Perfluorononyl p-toluenesulfonate is a perfluoroalkylating agent which is also used in the synthesis of polyfluoroalkylamines.
Check Digit Verification of cas no
The CAS Registry Mumber 864-23-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 864-23:
(5*8)+(4*6)+(3*4)+(2*2)+(1*3)=83
83 % 10 = 3
So 864-23-3 is a valid CAS Registry Number.

α,α,ω-TRIHYDRO-α-HALOPERFLUOROALKANES
Shilin, S. V.,Florensova, O. N.,Chernov, N. F.,Voronkov, M. G.
, p. 1697 - 1699 (2007/10/02)
A synthesis has been developed for α,α,ω-trihydrohaloperfluoroalkanes, H(CF2CF2)n*CH2X, where X is Cl or Br and n is 1 or 4.It is based on the cleavage of the aromatic sulfonate esters of α,α,ω-trihydroperfluoroalkan-α-ols by alkali metal halides.
