162397-88-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 162397-88-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,3,9 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 162397-88:
(8*1)+(7*6)+(6*2)+(5*3)+(4*9)+(3*7)+(2*8)+(1*8)=158
158 % 10 = 8
So 162397-88-8 is a valid CAS Registry Number.

Synthesis of novel monomers containing the Trifluorovinylidene-group and the Cyanato-group and polymers thereof

-

Page/Page column 25-26, (2010/11/24)

Novel hybrid monomers contaning both the aryltrifluorovyinyloxyether-group (TFVE-group) and the cyanato-group, their synthesis, and the synthesis of homo- and co-polymers made from these new hybridmonomers are disclosed. The said monomers are preferably of formula (III): wherein R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 can independently be selected from among a broad variety of substituents, R 11 is a single bond or is an alkylene group, R 13 and R 14 are both preferably F, and R 11 , R 15 and R 16 can be either F or H, Y and z are independent from each other and each Y and/or z can independently (in case q and/or n are more than 1) be selected from a chemical bond, SO 2 , CF 2 , CH 2 , CHF, CH(CH 3 ) 2 , isopropylene, hexafluoroisopropylene, n- or iso-C 1 -C 18 alkylene which may be partly or fully fluorinated, 0, NR 19 , N=N, CH=CH, -(C=O)-O-, -O-(C=O)-, CH=N, -C‰?C-, CHN-N=CH, alkyloxyalkylene having 1 to 18 carbon atoms which is optionally partly or fully fluorinated, S, Si(CH 3 ) 2 or wherein R 19 is hydrogen or C 1 -C 18 alkyl, Q has the same meaning as Y, m is 0 or 1, n is 0, or an integer between 1 and 6, o is 0 or an integer between 1 and 12, p is 0 or 1, and q is 0 or an integer between 1 and 6.
