850544-46-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 850544-46-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,5,4 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 850544-46:
(8*8)+(7*5)+(6*0)+(5*5)+(4*4)+(3*4)+(2*4)+(1*6)=166
166 % 10 = 6
So 850544-46-6 is a valid CAS Registry Number.

Protection against peroxynitrite-mediated nitration reaction by intramolecularly coordinated diorganoselenides

Kumar, Sangit,Singh, Harkesh B.,Wolmershaeuser, Gotthelf

, p. 382 - 393 (2008/10/09)

A series of intramolecularly Se...X (X = N, O) coordinated diorganoselenides and -sulfides are synthesized by using the heteroatom-directed lithiation route and characterized by multinuclear (1H, 13C, 77Se) NMR, IR spectroscopy, and electrospray mass spectrometry (ES-MS). The intramolecular Se...O interactions in diorganoselenides 26-31 have been studied by multinuclear NMR studies in solution and in the solid state by single-crystal X-ray crystallography. The protection against peroxynitrite-mediated nitration reaction (PN assay) by diorganoselenides/-sulfides (with and without intramolecular coordination) has been evaluated. The PN assay data of diorganoselenides reveal that the selenides 20-22, having a basic amino group (sp3-N donor) in close proximity of selenium, are more active compared to the diorganoselenides 16-19, having an imino group (sp2-N donor), and also show much higher protective action than the unsubstituted diorganoselenides 14 and 15. The diorganoselenides 16-31 were oxidized to corresponding selenoxides 44-59. The redox properties of the selenoxides 13 and 44-59 have been investigated by cyclic voltammetry and potentiometric titration experiments. Two redox potentials for in situ-generated ferrocenyl selenoxides (50, 54-59) were observed. The reduction of selenoxides 13 and 48 to ebselen (2) and selenide 20 with benzenethiol (PhSH) was monitored by ES-MS.
