Check Digit Verification of cas no

The CAS Registry Mumber 25944-71-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,4 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25944-71:
(7*2)+(6*5)+(5*9)+(4*4)+(3*4)+(2*7)+(1*1)=132
132 % 10 = 2
So 25944-71-2 is a valid CAS Registry Number.

New NLO stilbene derivatives bearing phosphonate ester electron-withdrawing groups

Belfield, Kevin D.,Chinna, Chandrasekhar,Schafer, Katherine J.

, p. 6131 - 6134 (1997)

The synthesis and characterization of a new class of electron donor-acceptor substituted stilbenes hearing a phosphonate ester as the electron-withdrawing functionality is described. Phosphorylation of aromatic rings was accomplished using Ni-catalyzed Arbuzov reactions, while Pd-catalyzed Heck-type coupling reactions were employed to construct the stilbene derivatives. Through determination of an electro-optic coefficient (r33), it was demonstrated that the phosphonate ester group is effective as an electron-withdrawing group for stilbene-based second-order NLO materials.

Visible-light-mediated phosphonylation reaction: formation of phosphonates from alkyl/arylhydrazines and trialkylphosphites using zinc phthalocyanine

Hosseini-Sarvari, Mona,Koohgard, Mehdi

, p. 5905 - 5911 (2021/07/12)

In this work, we developed a ligand- and base-free visible-light-mediated protocol for the photoredox syntheses of arylphosphonates and, for the first time, alkyl phosphonates. Zinc phthalocyanine-photocatalyzed Csp2-P and Csp3-P bond formations were efficiently achieved by reacting aryl/alkylhydrazines with trialkylphosphites in the presence of air serving as an abundant oxidant. The reaction conditions tolerated a wide variety of functional groups.

A case of chain propagation: α-aminoalkyl radicals as initiators for aryl radical chemistry

Constantin, Timothée,Juliá, Fabio,Leonori, Daniele,Sheikh, Nadeem S.

, p. 12822 - 12828 (2020/12/29)

The generation of aryl radicals from the corresponding halides by redox chemistry is generally considered a difficult task due to their highly negative reduction potentials. Here we demonstrate that α-aminoalkyl radicals can be used as both initiators and chain-carriers for the radical coupling of aryl halides with pyrrole derivatives, a transformation often employed to evaluate new highly reducing photocatalysts. This mode of reactivity obviates for the use of strong reducing species and was also competent in the formation of sp2 C-P bonds. Mechanistic studies have delineated some of the key features operating that trigger aryl radical generation and also propagate the chain process.
