Check Digit Verification of cas no

The CAS Registry Mumber 16597-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,9 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16597-50:
(7*1)+(6*6)+(5*5)+(4*9)+(3*7)+(2*5)+(1*0)=135
135 % 10 = 5
So 16597-50-5 is a valid CAS Registry Number.

Simplified beta-glycosylation of peptides

Zhang, Yonglian,Knapp, Spencer

, p. 2891 - 2903 (2018/05/08)

A simple and effective activating system for S-phenyl thioglycosides, namely N-iodosuccinimide and catalytic copper(I) triflate, promotes beta-O-glycosylation at the serine and threonine hydroxyls of “mono-,” di-, and tripeptides. The same activator combination promotes carboxamide beta-N-glycosylation of asparagine-containing mono-, di, and tri-peptides, as well as a nucleoside carboxamide and a sulfonamide. An important feature of the copper(I) triflate method is that undesired amide O-glycosylation is largely circumvented. For both sets of biologically important acceptor sites (HO– and –CONH2), a beta-GlcNAc-equivalent donor is demonstrated to provide the linkages efficiently. Streamlined deprotection sequences have been developed based on global hydrogenolysis that lead smoothly to the parent glycopeptides. The core glycopeptide region for biological protein N-glycosylation, represented by N4-(β-N-acetyl-D-2-glucosaminyl)-Asp-Gly-Thr-OH, has been prepared in solution, purified, and characterized as the fully deprotected (mono)glycosylated tripeptide.

Site-selective solid phase synthesis of carbonylated peptides

Waliczek, Mateusz,Kijewska, Monika,Stefanowicz, Piotr,Szewczuk, Zbigniew

, p. 1353 - 1365 (2015/06/16)

Abstract The aim of our research was to design an efficient method for the solid phase synthesis of carbonylated peptides. For this purpose, we designed and synthesized a fully protected derivative Fmoc-amino(2,5,5-trimetyhyl-1,3-dioxolan-2-yl)acetic acid

Aqueous phosphoric acid as a mild reagent for deprotection of tert-butyl carbamates, esters, and ethers

Li, Bryan,Berliner, Martin,Buzon, Richard,Chiu, Charles K.-F.,Colgan, Stephen T.,Kaneko, Takushi,Keene, Nandell,Kissel, William,Le, Tung,Leeman, Kyle R.,Marquez, Brian,Morris, Ronald,Newell, Lisa,Wunderwald, Silke,Witt, Michael,Weaver, John,Zhang, Zhijun,Zhang, Zhongli

, p. 9045 - 9050 (2007/10/03)

(Chemical Equation Presented) Aqueous phosphoric acid (85 wt %) is an effective, environmentally benign reagent for the deprotection of tert-butyl carbamates, tert-butyl esters, and tert-butyl ethers. The reaction conditions are mild and offer good selectivity in the presence of other acid-sensitive groups, including CBZ carbamates, azetidine, benzyl and methyl esters, TBDMS, and methyl phenyl ethers. The mildness of the reaction is further demonstrated in the synthesis of clarithromycin derivative 4, in which a tert-butyl ester is removed in the presence of cyclic carbamate, lactone, ketal, acetate ester, and epimerizable methyl ketone functionalities. The reaction preserves the stereochemical integrity of the substrates. The reactions are high yielding, and the workup is convenient.
