75961-62-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75961-62-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,6 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75961-62:
(7*7)+(6*5)+(5*9)+(4*6)+(3*1)+(2*6)+(1*2)=165
165 % 10 = 5
So 75961-62-5 is a valid CAS Registry Number.

Photocatalyzed ortho-Alkylation of Pyridine N-Oxides through Alkene Cleavage

Zhou, Wang,Miura, Tomoya,Murakami, Masahiro

supporting information, p. 5139 - 5142 (2018/05/30)

A photocatalyzed reaction of pyridine N-oxides with alkenes gives ortho-alkylated pyridines with cleavage of the carbon–carbon double bond. Benzyl and secondary alkyl groups are incorporated at the ortho position of pyridines in one pot.

Photochemistry of Stable Pyridinyl Radicals. Photolysis of N-Alkyl-4-(carboalkoxy)pyridinyls

Takagi, Katsuhiko,Ogata, Yoshiro

, p. 989 - 992 (2007/10/02)

Photoinduced decomposition of N-benzyl-4-carbethoxypyridinyl (1a), N-methyl- (1b) and N-benzyl-4-(carbomethoxy)pyridinyl (1c), and their mixture was studied in degassed acetonitrile.N-benzyl homologues (1a and 1c) were smoothly photolyzed to ethyl (or methyl) isonicotinate by loss of a benzyl group, whereas the N-methyl homologue (1b) was comparatively stable toward UV light; the rate of disappearance of 1c relative to that of 1b was 11:1.A mechanism is postulated, which involves the formation of an alkyl radical by C-N bond homolysis followed by attack on the pyridinyl radical to form dihydropyridines.This is supported by a plot of the yield of ethyl isonicotinate vs. the ratio of initial concentrations 0/0.Pyridinyl radicals 1 possess their absorption maxima at around 300, 395, and 630 nm; those at 300 and 395 nm maxima participate in this reaction.
