335-68-2 Usage
General Description
1,1,3,5,7,8-HEXACHLOROPERFLUOROOCTANE is a chemical compound that consists of eight carbon atoms, six chlorine atoms, and one fluorine atom. It is a member of the perfluoroalkyl compounds, which are known for their stability and resistance to heat, water, and oil. Due to these properties, 1,1,3,5,7,8-HEXACHLOROPERFLUOROOCTANE has been used in various industrial applications, including as a surfactant in the production of non-stick coatings and waterproofing fabrics. However, it has been found to be persistent in the environment and has the potential to bioaccumulate, leading to concerns about its impact on human health and the environment. As a result, 1,1,3,5,7,8-HEXACHLOROPERFLUOROOCTANE has been subject to regulatory restrictions in some countries.
Check Digit Verification of cas no
The CAS Registry Mumber 335-68-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 335-68:
(5*3)+(4*3)+(3*5)+(2*6)+(1*8)=62
62 % 10 = 2
So 335-68-2 is a valid CAS Registry Number.

Reaction of 1,2-Dichloroiodotrifluoroethane With Zinc
Eapen, K. C.,Tamborski, C.
, p. 421 - 424 (2007/10/02)
The zinc coupling reaction of 1,2-dichloroiodotrifluoroethane (I) in acetic anhydride-methylene chloride has been reinvestigated in more detail than its original disclosure.The expected coupling product C4F6Cl4 was shown to be an isomeric mixture of three components, CF2ClCFClCFClCF2Cl (II, 80percent), CFCl2CF2CF2CFCl2 (IIa, 15percent) and CF2ClCFClCF2CFCl2 (IIb, 5percent).In addition, other products e.g.CF2-CFCl, C6F9Cl5 and C8F12Cl6 were formed in minor quantities.A probable mode of formation of various byproducts via initial formation of CF2-CFCl and subsequent telomerization is presented.
