51431-54-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51431-54-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,4,3 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 51431-54:
(7*5)+(6*1)+(5*4)+(4*3)+(3*1)+(2*5)+(1*4)=90
90 % 10 = 0
So 51431-54-0 is a valid CAS Registry Number.

Synthesis of 3-arylindole derivatives from nitroalkane precursors

Huang, Chia-Yu,Kuo, Chun-Wei,Konala, Ashok,Yang, Tang-Hao,Lin, Lyu,Chen, Yu-Wen,Kavala, Veerababurao,Yao, Ching-Fa

, p. 96049 - 96056 (2016/10/25)

3-Arylindole derivatives were synthesized by Cu(i) catalysed intramolecular Ullmann coupling of 2-bromoarylaminoalkanes. 2-Bromoarylaminoalkanes were synthesized from 2-bromoarylnitroalkanes, which in turn prepared through AlCl3-mediated Friede

Chemoselective debezylation of the N-1-phenylethyl group in 2-oxazolidinones by the anisole-methanesulfonic acid system

Sugiyama, Shigeo,Morishita, Kenji,Chiba, Mariko,Ishii, Keitaro

, p. 637 - 648 (2007/10/03)

The chemoselective removal of N-1-phenylethyl group in 2-oxazolidinones by the anisole-methanesulfonic acid system was investigated. Optically active 4,5-cis- and 4,5-trans-diphenyl-2-oxazolidinones (1a-d) were easily synthesized from dl-stilbene oxides (trans- and cis-7a) using this debenzylation.
