Check Digit Verification of cas no

The CAS Registry Mumber 40269-01-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,6 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40269-01:
(7*4)+(6*0)+(5*2)+(4*6)+(3*9)+(2*0)+(1*1)=90
90 % 10 = 0
So 40269-01-0 is a valid CAS Registry Number.

Stereoselective synthesis of resorcylic acid lactone Cochliomycin B

Nagalatha,Siva Ganesh,Venkat Narsaiah

, (2021/09/22)

The total synthesis of 14-membered resorcylic acid lactone, Cochliomycin B has prescribed, in a convergent manner, from readily available starting materials, D-galactose, L-aspartic acid and ethyl acetoacetate. The key reactions involved in the synthesis are Julia-Kocienski olefination, E-selective Horner-Wadsworth-Emmons olefination and intramolecular lactonization.

Localization-controlled two-color luminescence imaging: Via environmental modulation of energy transfer in a multichromophoric species

Bonaccorsi, Paola,Papalia, Teresa,Barattucci, Anna,Salerno, Tania M. G.,Rosano, Camillo,Castagnola, Patrizio,Viale, Maurizio,Monticone, Massimiliano,Campagna, Sebastiano,Puntoriero, Fausto

supporting information, p. 4733 - 4738 (2018/04/03)

We prepared a bichromophoric species 1, made of two different bodipy dyes bridged by a d-galactose unit. 1 exhibits different emission spectra when located in different compartments of biological systems, independently of its concentration. This is an unprecedented feature for a single multicomponent molecule and is due to the dependence on the environment of the photoinduced energy transfer process occurring between its bodipy subunits. Therefore, 1 can give useful information about cell composition and ultimately anomalies without requiring the simultaneous use of several different compounds, paving the way for the use of environment-controlled inter-component energy transfer to gain cell information based on luminescence imaging.

Allylic Azide Rearrangement in Tandem with Huisgen Cycloaddition for Stereoselective Annulation: Synthesis of C-Glycosyl Iminosugars

Moynihan, Lorna,Chadda, Rekha,McArdle, Patrick,Murphy, Paul V.

supporting information, p. 6226 - 6229 (2016/01/09)

Allylic azide rearrangement is used in tandem with intramolecular azide-alkene cycloaddition to give a triazoline that when subsequently decomposed in the presence of a nucleophile gives piperidines. The tandem reaction gives two stereocenters that are generated with high control. The formation of the piperidines required the presence of innate conformational constraint. The applicability of the annulation reaction is demonstrated by the synthesis of iminosugars. A proposal is included to account for the observed stereoselectivity, which is influenced by the precursor structure.
