50880-39-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50880-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,8,8 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50880-39:
(7*5)+(6*0)+(5*8)+(4*8)+(3*0)+(2*3)+(1*9)=122
122 % 10 = 2
So 50880-39-2 is a valid CAS Registry Number.

Synthesis of 5,12-Diazapentacenes and Their Properties

Garcia, Rosalva C.,Pech, Matthew J.,Sommer, Roger,Gorman, Christopher B.

, p. 15079 - 15086 (2019/11/21)

An efficient synthesis via a precursor route to a new class of linear dialkyldiaminoazapentacenes is reported. The synthetic route involves the coupling of 4-substituted aniline derivatives to 2,5-dibromoterephthalonitrile via Buchwald-Hartwig amination f

Hole Transfer Processes in meta- and para-Conjugated Mixed Valence Compounds: Unforeseen Effects of Bridge Substituents and Solvent Dynamics

Sch?fer, Julian,Holzapfel, Marco,Mladenova, Boryana,Kattnig, Daniel,Krummenacher, Ivo,Braunschweig, Holger,Grampp, Günter,Lambert, Christoph

supporting information, p. 6200 - 6209 (2017/05/09)

To address the question whether donor substituents can be utilized to accelerate the hole transfer (HT) between redox sites attached in para- or in meta-positions to a central benzene bridge, we investigated three series of mixed valence compounds based o

Fluorene as the π-spacer for new two-photon absorption chromophores

Cheng, Jian-Zhang,Lin, Chao-Chen,Chou, Pi-Tai,Chaskar, Atul,Wong, Ken-Tsung

experimental part, p. 734 - 739 (2011/03/19)

We report herein the design and synthesis of two new quadrupolar D-π-A-π-D chromophores containing diphenyl amine and dicyanobenzene or 2,1,3-benzothiadiazole as electron donor (D) and acceptor (A), respectively, which are bridged by fluorene linkage (π).
