203255-90-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 203255-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,2,5 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203255-90:
(8*2)+(7*0)+(6*3)+(5*2)+(4*5)+(3*5)+(2*9)+(1*0)=97
97 % 10 = 7
So 203255-90-7 is a valid CAS Registry Number.

Novel perfluorocyclohexylation with bis(perfluorocyclohexane carbonyl) peroxide

Sawada, Hideo,Kurachi, Minaka,Kawase, Tokuzo,Takishita, Katsuhisa,Tanedani, Toshiyuki,Aoshima, Kazuyoshi

, p. 153 - 154 (1998)

A new bis(perfluorocyclohexane carbonyl) peroxide was prepared by the reaction of the corresponding acyl fluoride and hydrogen peroxide. This peroxide was applicable for the direct introduction of perfluorocyclohexyl group into various organic molecules such as acrylic acid oligomer, benzene and polystyrene; in particular interest, not only equatorial but also axial conformational isomers were isolated in phenylperfluorocyclohexane thus obtained.

Novel perfluoroalkyl vinyl ether compound, process for preparing copolymer by using the compound, and optical plastic materials comprising copolymer prepared by the process

-

Page/Page column 7-8, (2008/06/13)

Disclosed herein are a novel perfluoroalkyl vinyl ether compound, a process for preparing a copolymer by using the perfluoroalkyl vinyl ether compound, and an optical plastic material comprising a copolymer prepared by the process. More specifically, the perfluoroalkyl vinyl ether has a particular molecular structure; the process is performed by copolymerizing the perfluoroalkyl vinyl ether compound with a common fluorinated olefin in the presence of a perfluorinated radical initiator; and, the optical plastic material comprises a copolymer prepared by the process and optionally a dopant. The copolymerization of the perfluoroalkyl vinyl ether with a common fluorinated olefin can provide a copolymer having a high molecular weight. In addition, appropriate control of the composition of the monomers can provide a completely amorphous copolymer. Since the polymer prepared by the process exhibits excellent thermal properties and is substantially transparent in the UV and near IR regions, it can be usefully applied to various optical plastic materials. Furthermore, a preform for a GI type plastic optical fiber fabricated by using the copolymer and the dopant has a high Tg, thus being stable, and a parabolic refractive index profile due to the presence of the dopant.
