40292-19-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40292-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,9 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40292-19:
(7*4)+(6*0)+(5*2)+(4*9)+(3*2)+(2*1)+(1*9)=91
91 % 10 = 1
So 40292-19-1 is a valid CAS Registry Number.

Synthesis of Benzophenone Nucleosides and Their Photocatalytic Evaluation for [2+2] Cycloaddition in Aqueous Media

Ga?, Nadine,Wagenknecht, Hans-Achim

, p. 6661 - 6668 (2015)

Four benzophenone nucleosides that are para-substituted (-NH2, -NMe2, -OMe, and -Me) in relation to the carbonyl group were synthesized and characterized by their optical properties. The electron-donating character of the substituent

Coumarin-surfactant modified polyoxometalate catalyzed cross dehydrogenative coupling of benzyl alcohol with the: Para -C-H of unprotected aniline

Xu, Qian,Yu, Gang,Liu, Min,Peng, Chang,Banks, M. Katherine,Xu, Weijian,Wu, Ruoxi,Lu, Yanbing

, p. 5133 - 5136 (2018/10/24)

This paper presents a novel method for synthesizing para-aminobenzophenone and its derivatives (p-ABPs) using a coumarin-surfactant modified polyoxometalate as the catalyst. Preliminary mechanistic studies indicate that the reaction has undergone an oxidative cross dehydrogenative coupling process. This method has the advantages of an easy process, a convenient raw material source, safe and green oxidants, and tolerances of several functional groups.

Studies on the Insecticidal Activities of Some New N-Benzoyl-N'-Arylureas

Carmellino, Maria L.,Pagani, Giuseppe,Pregnolato, Massimo,Terreni, Marco,Caprioli, Vincenzo,Zani, Franca

, p. 227 - 236 (2007/10/03)

This paper reports the synthesis and the insecticidal activities of some N-benzoyl-N'-arylureas 4-arylsubstituted with alkylated or halogenated aroyl moieties. The compounds, tested against some representative insect species, displayed very high activity against Aedes aegypti, especially the halosubstituted derivatives. None of the newly synthesized compounds showed genotoxic activity in the Bacillus subtilis rec-assay and in the Salmonella-microsome test.
