168417-28-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 168417-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,4,1 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 168417-28:
(8*1)+(7*6)+(6*8)+(5*4)+(4*1)+(3*7)+(2*2)+(1*8)=155
155 % 10 = 5
So 168417-28-5 is a valid CAS Registry Number.

Reactions of fluorine-containing N-sulfinylamides with carboxylic acids and acid anhydrides

Zhu, ShiZeng,Xu, Bin,Zhang, Jie

, p. 203 - 206 (1995)

Heating N-sulfinyl perfluoroalkane sulfonylamides, RfSO2NSO, or N-sulfinylpentafluoroaniline, C6H5NSO, with carboxylic acids in the presence of catalytic amounts of SOCl2 gave N-perfluoroalkane sulfonylamides, RfSO2NHCOR, or N-pentafluorophenylamides, C6F5NHCOR, respectively.Acid anhydrides reacted similarly with RfSO2NSO or C6F5NSO to form N-perfluoroalkane sulfonylimides or N-pentafluorophenylimides. - Keywords: N-sulfinylamides; Carboxylic acids; Acid anhydrides

Reactions of N-(perfluorophenyl)carbonimidoyl dichloride with aromatic acids and their derivatives in the presence of AlCl3. Formation of 2-(perfluorophenyl)isoindoline-1,3-dione and its derivatives

Petrova,Platonov

, p. 218 - 226 (2007/10/03)

Reactions of N-(perfluorophenyl)carbonimidoyl dichloride with benzoic acid, benzoyl chloride, ethyl benzoate, and also with phthalic acid, phthaloyl dichloride, and phthalic anhydride in the presence of AlCl3 at 170°C afford2-(perfluorophenyl)isoindoline-1,3-dione. With benzoic acid and benzoyl chloride form also 2-(perfluorophenyl)-3-[(perfluorophenyl)imino] isoindolin-1-one. In reactions with compounds of the benzene series arise also derivatives of arylimidoyl chlorides and amide type compounds containing a CONHC6F5 moiety. 2005 Pleiades Publishing, Inc.
