30319-44-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 30319-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,3,1 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 30319-44:
(7*3)+(6*0)+(5*3)+(4*1)+(3*9)+(2*4)+(1*4)=79
79 % 10 = 9
So 30319-44-9 is a valid CAS Registry Number.

Synthesis of a Tridecasaccharide Lipooligosaccharide Antigen from the Opportunistic Pathogen Mycobacterium kansasii

Bai, Bing,Liu, Yu-Hsuan,Lowary, Todd L.,Shen, Ke

supporting information, p. 24859 - 24863 (2021/10/25)

The outer surfaces of mycobacteria, including the organism that causes tuberculosis, are decorated with an array of immunomodulatory glycans. Among these are lipooligosaccharides (LOSs), a class of molecules for which the function remains poorly understoo

Total syntheses of schizandriside, saracoside and (±)-isolariciresinol with antioxidant activities

Sampei, Mana,Arai, Midori A.,Ishibashi, Masami

, p. 651 - 654 (2018/04/16)

Lignans are widely distributed in plants and exhibit significant pharmacological effects, including anti-tumor and antioxidative activities. Here, we describe the total synthesis of schizandriside (1), a compound we previously isolated from Saraca asoca b

Stereoselective Epimerizations of Glycosyl Thiols

Doyle, Lisa M.,O'Sullivan, Shane,Di Salvo, Claudia,McKinney, Michelle,McArdle, Patrick,Murphy, Paul V.

supporting information, p. 5802 - 5805 (2017/11/10)

Glycosyl thiols are widely used in stereoselective S-glycoside synthesis. Their epimerization from 1,2-trans to 1,2-cis thiols (e.g., equatorial to axial epimerization in thioglucopyranose) was attained using TiCl4, while SnCl4 promoted their axial-to-equatorial epimerization. The method included application for stereoselective β-d-manno- and β-l-rhamnopyranosyl thiol formation. Complex formation explains the equatorial preference when using SnCl4, whereas TiCl4 can shift the equilibrium toward the 1,2-cis thiol via 1,3-oxathiolane formation.
