404-28-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 404-28-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 404-28:
(5*4)+(4*0)+(3*4)+(2*2)+(1*8)=44
44 % 10 = 4
So 404-28-4 is a valid CAS Registry Number.

Unique para-effect in electron ionization mass spectra of bis(perfluoroacyl) derivatives of bifunctional aminobenzenes

Tretyakov, Kirill V.,Todua, Nino G.,Borisov, Roman S.,Zaikin, Vladimir G.,Stein, Stephen E.,Mikaia, Anzor I.

body text, p. 2529 - 2532 (2011/12/02)

A new kind of 'para-effect' under electron ionization (EI) conditions has been discovered for a series of bis(perfluoroacyl) derivatives of o-, m- and p-phenylenediamines, -hydroxybenzeneamines and -mercaptobenzeneamines of a common structure RCOX-C6H4-NHCOR (X=NH, S, O; R=CF3, C2F5, C3F7). Only the para-isomers showed successive loss of a radical RCO? and a molecule RCN, leading to very intense peaks in the EI spectra. The composition and the origin of the [M-COR-NCR]+ ions were confirmed by exactmassmeasurements and linked scan experiments. The proposedmechanism of their formation takes into account likely para-quinoid structures of the precursor ions. A similar rearrangement has not been observed for para-isomers in the series of bis(perfluoroacyl) derivatives of benzenediols, mercaptophenols and dimercaptobenzenes.
