59345-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 59345-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,3,4 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 59345-42:
(7*5)+(6*9)+(5*3)+(4*4)+(3*5)+(2*4)+(1*2)=145
145 % 10 = 5
So 59345-42-5 is a valid CAS Registry Number.

Visible-Light-Promoted Metal-Free Aerobic Oxidation of Primary Amines to Acids and Lactones

Cheng, Xiaokai,Yang, Bo,Hu, Xingen,Xu, Qing,Lu, Zhan

, p. 17566 - 17570 (2016/11/29)

A unique metal-free aerobic oxidation of primary amines via visible light photocatalytic double carbon–carbon bonds cleavage and multi carbon–hydrogen bonds oxidation was observed. Aerobic oxidation of primary amines could be controlled to afford acids by using dioxane with 18 W CFL, and lactones by using DMF with 8 W green LEDs, respectively. A plausible mechanism was proposed based on control experiments. This observation showed direct evidences for the fragmentation in the aerobic oxidation of aliphatic primary amines.

Synthesis of γ-, δ-, and ε-lactams by asymmetric transfer hydrogenation of N-(tert-butylsulfinyl)iminoesters

Guijarro, David,Pablo, Oscar,Yus, Miguel

, p. 3647 - 3654 (2013/05/22)

Highly enantiomerically enriched γ- and δ-lactams have been prepared by a simple and very efficient procedure that involves the asymmetric transfer hydrogenation of N-(tert-butylsulfinyl)iminoesters followed by desulfinylation of the nitrogen atom and spo

Fjord Region 3,4-Diol 1,2-Epoxides and Other Derivatives in the 1,2,3,4- and 5,6,7,8-Benzo Rings of the Carcinogen Benzochrysene

Utermoehlen, Clifford M.,Singh, Mahatam,Lehr, Roland E.

, p. 5574 - 5582 (2007/10/02)

Dihydrodiol and diol epoxide derivatives of the carcinogen benzochrysene (BgCh) have been prepared to probe structural factors involved in the carcinogenesis and mutagenesis of polycyclic aromatic hydrocarbons.Preparation of 1,2-dihydrobenzochrysen-4(3H)-one (6) and 7,8-dihydrobenzochrysen-5(6H)-one (11), ketones suitable for further elaboration to potential metabolites of benzochrysene in the 1,2,3,4- and 5,6,7,8-benzo rings, respectively, was achieved through two cyclization steps.Photochemical closure of 2-(1- or 2-naphthyl)styrene derivatives 4 and 9 aff orded chrysene and benzophenanthrene ring systems with a butyric ester/acid side chain poised for a second ring closure (acid-catalyzed) to the desired ketones.Preparation of pure BgCh 3,4-diol 1,2-epoxides 23 and 24 from the dihydrodiol diester 14 by conversion to separable trans bromohydrins, cyclization to the epoxides, and hydrolysis of the acetates was found to be more successful than preparation from the dihydrodiol 15.
