938-24-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 938-24-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 938-24:
(5*9)+(4*3)+(3*8)+(2*2)+(1*4)=89
89 % 10 = 9
So 938-24-9 is a valid CAS Registry Number.

Synthesis, characterization, and some reactions of the tricarbonylchromium complexes of 1,3-indandione and ninhydrin

Leinweber, Dirk,Wartchow, Rudolf,Butenschoen, Holger

, p. 167 - 179 (1999)

The syntheses and characterization of the tricarbonylchromium complexes of 1,3-indandione and ninhydrin are described. As the direct complexation proved unsuccessful, the acetal route was tried. Although some complexes were obtained, complex deacetalization did not work in the case of ninhydrin. Finally, the oxidation of tricarbonyl(η6-1,3-indandione)chromium(0) with dimethyldioxirane gave the ninhydrin complex in 75% yield in equilibrium with the indantrione complex. The latter reacts in hetero Diels-Alder reactions with dienes with diastereoselective formation of spiro anellated pyran derivatives.

Design, synthesis, and characterization of oxadiazolopyrazine analogs with application as anticancer agents

Chang, Tzu-Ting,Chen, Chia-Ling,Chen, Wei-Chia,Chen, Wei-Sheng,Hsieh, Feng-Chun,Li, Wen-Shan

, (2021/12/23)

Here, we describe the synthesis and evaluation of a class of cell-permeable indeno-oxadiazolopyrazine analogs as the anticancer agents. A new and facile approach to the synthesis of substituted analogs of indeno-oxadiazolopyrazine is illustrated. We find that the designed indeno-oxadiazolopyrazines, 3, 4, 10, 11, 15, and 16, act as potent anticancer agents compared to camptothecin, topoisomerase I inhibitor. These observations suggest that the electron-donating group (methoxy) at the C-5, C-6, and C-8 positions or electron-withdrawing group (fluoro) at the C-6 and C-7 positions on the A ring of indeno-oxadiazolopyrazines is required for antiproliferative activities against MDA-MB-231, BT549, and MCF7 cell lines.

Facile synthesis of 1,2,3-tricarbonyls from 1,3-dicarbonyls mediated by cerium(IV) ammonium nitrate

Sivan, Akhil,Deepthi, Ani

supporting information, p. 1890 - 1893 (2014/03/21)

A mild and efficient protocol for the synthesis of vicinal tricarbonyl compounds from β-dicarbonyls in a single step using cerium(IV) ammonium nitrate as a catalytic oxidant is described. Ease of execution, wide substrate scope and the suitability for the synthesis of commercially important compounds like ninhydrin, alloxan and oxoline make this reaction particularly noteworthy.
