Uses
1H,1H-Perfluoro-1-nonanol is used to produce other chemicals. For example, it is used to produce Trifluoro-methanesulfonic acid 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,9-heptadecafluoro-nonyl ester. This reaction needs reagent Pyridine and solvent CHCl3
Check Digit Verification of cas no
The CAS Registry Mumber 423-56-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 423-56:
(5*4)+(4*2)+(3*3)+(2*5)+(1*6)=53
53 % 10 = 3
So 423-56-3 is a valid CAS Registry Number.

Thermal desulfurization of (Alkoxymethyl)thiiranes
Nalet'Ko,Pervova,Gorbunova,Zapevalov, A. Ya,Toporova,Saloutin
, p. 2120 - 2124 (2015/02/02)
Reaction of (alkoxymethyl)oxiranes with thiourea in methanol has afforded the corresponding thiiranes, and catalyst-free thermal desulfurization of the products has been studied. The major products of desulfurization are alcohols and alkenes, both in the cases of (polyfluoroalkyloxymethyl)thiiranes and their non-fluorinated analogs. Longer alkyl chain in thiiranes favors formation of alcohols over alkenes formation in the course of desulfurization.
