Check Digit Verification of cas no

The CAS Registry Mumber 1646-54-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1646-54:
(6*1)+(5*6)+(4*4)+(3*6)+(2*5)+(1*4)=84
84 % 10 = 4
So 1646-54-4 is a valid CAS Registry Number.

Porous Organic Polymer Films with Tunable Work Functions and Selective Hole and Electron Flows for Energy Conversions

Gu, Cheng,Huang, Ning,Chen, Youchun,Zhang, Huanhuan,Zhang, Shitong,Li, Fenghong,Ma, Yuguang,Jiang, Donglin

, p. 3049 - 3053 (2016)

Organic optoelectronics are promising technologies for energy conversion. However, the electrode interlayer, a key material between active layers and conducting electrodes that controls the transport of charge carriers in and out of devices, is still a chemical challenge. Herein, we report a class of porous organic polymers with tunable work function as hole- and electron-selective electrode interlayers. The network with organoborane and carbazole units exhibits extremely low work-function-selective electron flow; while upon ionic ligation and electro-oxidation, the network significantly increases the work function and turns into hole conduction. We demonstrate their outstanding functions as anode and cathode interlayers in energy-converting solar cells and light-emitting diodes.

Synthesis and structure of zinc(II) and cobalt(II) coordination polymers involving the elongated 2′,3′,5′,6′ tetramethylterphenyl-4, 4″-dicarboxylate ligand

Lozan, Vasile,Makhloufi, Gamall,Druta, Vadim,Bourosh, Paulina,Kravtsov, Victor Ch.,Marangoci, Narcisa,Heering, Christian,Janiak, Christoph

The elongated linker 2′,3′,5′,6′-tetramethylterphenyl-4,4″-dicarboxylic acid (H2L) was employed in the synthesis of zinc(II) and cobalt(II) coordination polymers with single or mixed bridging ligands. Seven compounds, that include the solvate H

The equilibria and conversions between three excited states: The le state and two charge transfer states, in twisted pyrene-substituted tridurylboranes

Ren, Ming-Guang,Mao, Mao,Song, Qin-Hua

, p. 2970 - 2972 (2012)

Excited-state conversions were observed from a series of twisted pyrene-substituted tridurylboranes, corresponding to a locally excited (LE) state, a more planar charge transfer (CT) state with a higher fluorescence quantum efficiency, and a more twisted

Effect of Branching on the Delayed Fluorescence and Phosphorescence of Simple Borylated Arylamines

A donor-π-acceptor strategy is being well exploited in several fields in view of their robust optical properties. However, the impact of branching in quadrupolar [A-(π-D)2] and octupolar [A-(π-D)3] molecules in comparison to parent d

A study on the synthesis, characterization, structural optimization, and conformational behaviors of bromo-substituted pyromelliticdiimide-based [2+2] macrocycle as structural units of covalently linked molecular tubes

Bandyopadhyay, Arkasish,Halim, Md. Ershad,Hossain, Md. Elius,Shinmyozu, Teruo

, (2020/04/17)

Synthesis and structural, photo physical, and conformational behaviors at variable temperature and structural optimization of the pyromelliticdiimide-based bromo-substituted [2 + 2] macrocycles are described. Cyclization of the diamine (3) with dianhydride (4) in THF, followed by dehydration of the resultant amic acids resulted in the isolation of the bromo-substituted [2 + 2] macrocycle 1 (4.5%). The dynamic temperature-dependent 1H NMR spectra and MO calculations revealed the presence of two possible conformers for the [2 + 2] macrocycle 1. The UV/Vis spectrum of 1 reveals the presence of a weak intramolecular CT interaction of electron-withdrawing pyromelliticdiimide moiety with the electron-donating hexyloxy-substituted xylyl moiety. The cyclic voltammetric measurement shows two two-electron reversible reduction processes.
