Check Digit Verification of cas no

The CAS Registry Mumber 219518-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,1 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 219518-19:
(8*2)+(7*1)+(6*9)+(5*5)+(4*1)+(3*8)+(2*1)+(1*9)=141
141 % 10 = 1
So 219518-19-1 is a valid CAS Registry Number.

Stereoselective Phenylselenoglycosylation of Glycals Bearing a Fused Carbonate Moiety toward the Synthesis of 2-Deoxy-β-galactosides and β-Mannosides

Li, Zhongjun,Meng, Shuai,Yao, Wang,Zhong, Wenhe

supporting information, (2020/04/09)

A phenylselenoglycosylation reaction of glycal derivatives mediated by diphenyl diselenide and phenyliodine(III) bis(trifluoroacetate) under mild conditions is described. Stereoselective glycosylation has been achieved by installing fused carbonate on those glycals. 3,4-O-Carbonate galactals and 2,3-O-carbonate 2-hydroxyglucals are converted into corresponding glycosides in good yields with excellent β-selectivity, resulting in 2-phenylseleno-2-deoxy-β-galactosides and 2-phenylseleno-β-mannosides which are good precursors of 2-deoxy-β-galactosides and β-mannosides, respectively.

Phosphotungstic acid as a novel acidic catalyst for carbohydrate protection and glycosylation

Chen, Jyun-Siao,Sankar, Arumugam,Lin, Yi-Jyun,Huang, Po-Hsun,Liao, Chih-Hsiang,Wu, Shen-Shen,Wu, Hsin-Ru,Luo, Shun-Yuan

, p. 33853 - 33862 (2019/11/11)

This work demonstrates the utilization of phosphotungstic acid (PTA) as a novel acidic catalyst for carbohydrate reactions, such as per-O-acetylation, regioselective O-4,6 benzylidene acetal formation, regioselective O-4 ring-opening, and glycosylation. These reactions are basic and salient during the synthesis of carbohydrate-based bioactive oligomers. Phosphotungstic acid's high acidity and eco-friendly character make it a tempting alternative to corrosive homogeneous acids. The various homogenous acid catalysts were replaced by the phosphotungstic acid solely for different carbohydrate reactions. It can be widely used as a catalyst for organic reactions as it is thermally stable and easy to handle. In our work, the reactions are operated smoothly under ambient conditions; the temperature varies from 0 °C to room temperature. Good to excellent yields were obtained in all four kinds of reactions.

Immobilization of UDP-Galactose on an Amphiphilic Resin

Bevan, Jessica G. M.,Louren?o, Eva C.,Chaves-Ferreira, Miguel,Rodrigues, Jo?o A.,Rita Ventura

supporting information, p. 908 - 914 (2018/02/27)

Nucleotide sugars are activated sugar precursors used by glycosyltransferases to form glycans. Here we report the first examples of resin-bound nucleotide sugars: fluorinated UDP-galactose and UDP-galactose. They were conjugated to a polyethylene glycol resin through the C6 position with an SMCC linker in good to excellent yields. This synthesis represents an efficient method to access resin-bound nucleotide sugars in a modular approach that enables modifications of the sugar or nucleotide before conjugation. The system has been conceived as a new chemistry-based screening system for enzymes that use UDP-galactose.

Simple and Practical Real-Time Analysis of Solid-Phase Reactions by Thin-Layer Chromatography

Wu, Chia-Hui,Chen, Chun C.,Lin, Su-Ching,Wang, Cheng-Chung

, p. 1430 - 1436 (2018/05/15)

Solid-phase synthesis is a practical approach for simplifying the time-consuming and routine purification steps in the preparation of numerous naturally occurring molecules; however, studying such reactions is difficult due to the lack of a convenient monitoring method. By using thin-layer chromatography in conjunction with a photolabile linker on a resin, we developed a convenient and simple method for monitoring solid-phase reactions in real time by thin-layer chromatography. This method provides a user-friendly protocol for examining reaction conditions for solid-state syntheses.
