Check Digit Verification of cas no

The CAS Registry Mumber 59957-75-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,9,5 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 59957-75:
(7*5)+(6*9)+(5*9)+(4*5)+(3*7)+(2*7)+(1*5)=194
194 % 10 = 4
So 59957-75-4 is a valid CAS Registry Number.

A study on the antioxidant activity of pyridylselenium compounds and their slow release from poly(acrylamide) hydrogels

Dhau, Jaspreet S.,Singh, Avtar,Singh, Amritpal,Sooch, Balwinder S.

, p. 687 - 699 (2014)

The antioxidant activity of pyridylselenium compounds has been evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical and nitric oxide (NO) scavenging methods. Pyridylselenium compounds have shown far superior (100-1000 times) antioxidant property than ebselen. The control release of bis(2-pyridyl) diselenide from poly(acrylamide) hydrogels has been studied in order to evaluate its release mechanism and diffusion coefficient. The later study also demonstrates that the pyridylselenium loading into the polymer matrix increases the magnitude and the rate of the radical scavenging activity of the poly(acrylamide) hydrogels.

A new and convenient route to 2,2′-dipyridyl diselenide/ditelluride and some of their alkyl/aryl derivatives through BF3-complexed pyridyl carbanion

Bhasin,Bhandal,Singh,Singh,Singh,Singh

, p. 1319 - 1325 (2002)

Synthesis of 2,2′-dipyridyl diselenide/ditelluride and some alkyl/aryl pyridyl selenide/telluride is reported.

A novel and convenient synthesis towards 2-pyridylselenium compounds: X-ray crystal structure of 4,4′-dimethyl-2,2′-dipyridyl diselenide and tris(2-pyridylseleno)methane

Bhasin,Singh, Jaspreet

, p. 71 - 76 (2002)

Various 2,2′-dipyridyl diselenides were prepared by a simple and convenient method employing non-cryogenic conditions. The diselenide anion, Se22- formed by reducing elemental selenium with 100% hydrazine hydrate in sodium hydroxide reacts in situ with 2-bromopyridines to afford the title compounds in good to excellent yields. Hydrazine hydrate readily cleaves the selenium-selenium bond in these diselenides to generate 2-pyridylselenolate anion, which reacts with halomethanes to afford 2-pyridylseleno methanes. X-ray crystal structure of 4,4′-dimethyl-2,2′-dipyridyl diselenide (4) and tris(2-pyridylseleno)methane (10) is described.

Synthesis of organoselenyl isoquinolinium imidesviairon(iii) chloride-mediated tandem cyclization/selenation ofN′-(2-alkynylbenzylidene)hydrazides and diselenides

Cai, Zhong-Jian,Ji, Shun-Jun,Li, Fang-Hui,Wang, Dian-Liang,Wu, Bing,Yao, Hai-Feng

supporting information, p. 7577 - 7584 (2020/10/14)

This report describes the synthesis of organoselenyl isoquinolinium imides through a tandem cyclization betweenN′-(2-alkynylbenzylidene)hydrazides and diselenides. The reaction was carried out at room temperature under an ambient atmosphere using cheap iron(iii) chloride as the metallic source. The strategy shows good tolerance to a broad range ofN′-(2-alkynylbenzylidene)hydrazides and diselenides, and forms C-N and C-Se bonds in one step. The obtained product is further transformed into a bioactiveH-pyrazolo[5,1-a]isoquinoline skeleton easilyviaa silver catalyzed [3 + 2] cycloaddition.

Rhodium-Catalyzed Carbene Transfer Reactions for Sigmatropic Rearrangement Reactions of Selenium Ylides

Jana, Sripati,Koenigs, Rene M.

supporting information, p. 3653 - 3657 (2019/05/24)

The rearrangement of selenium ylides is even today almost unexplored, although it would provide access to important organoselenium compounds with broad downstream applications. In this report, the first systematic study of sigmatropic rearrangement reactions of selenium ylides using a simple rhodium catalyst with catalyst loadings as low as 0.01 mol % is described. Selenium oxide pyrolysis of the rearrangement products gives access to important 1,1-disubstituted butadienes.
