3189-40-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3189-40-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,8 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3189-40:
(6*3)+(5*1)+(4*8)+(3*9)+(2*4)+(1*0)=90
90 % 10 = 0
So 3189-40-0 is a valid CAS Registry Number.

Visible Light Promoted Synthesis of Indoles by Single Photosensitizer under Aerobic Conditions

Liu, Wen-Qiang,Lei, Tao,Song, Zi-Qi,Yang, Xiu-Long,Wu, Cheng-Juan,Jiang, Xin,Chen, Bin,Tung, Chen-Ho,Wu, Li-Zhu

, p. 3251 - 3254 (2017)

The construction of substituted indole skeletons is always an important concern of synthetic chemists because of its prevalent structure found in natural products and biological molecules. Here, we succeeded in preparing indoles and their derivatives from

Tandem Blaise-Nenitzescu reaction: One-pot synthesis of 5-hydroxy-α-(aminomethylene)benzofuran-2(3H)-ones from nitriles

Chun, Yu Sung,Ryu, Ka Yeon,Kim, Ju Hyun,Shin, Hyunik,Lee, Sang-Gi

supporting information; experimental part, p. 1317 - 1319 (2011/04/22)

In contrast to the reaction of benzoquinones with β-enaminoesters providing indoles (Nenitzescu reaction), the tandem one-pot reaction of the Blaise reaction intermediate, zinc bromide complex of β-enaminoesters, with benzoquinone affords 5-hydroxy-α-(ami

Indolequinone antitumor agents: Correlation between quinone structure, rate of metabolism by recombinant human NAD(P)H:quinone oxidoreductase, and in vitro cytotoxicity

Beall, Howard D.,Winski, Shannon,Swann, Elizabeth,Hudnott, Anna R.,Cotterill, Ann S.,O'Sullivan, Noeleen,Green, Stephen J.,Bien, Richard,Siegel, David,Ross, David,Moody, Christopher J.

, p. 4755 - 4766 (2007/10/03)

A series of indolequinones bearing various functional groups has been synthesized, and the effects of substituents on the metabolism of the quinones by recombinant human NAD(P)H: quinone oxidoreductase (NQO1) were studied. Thus 5-methoxyindolequinones wer
