77667-56-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77667-56-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,6 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77667-56:
(7*7)+(6*7)+(5*6)+(4*6)+(3*7)+(2*5)+(1*6)=182
182 % 10 = 2
So 77667-56-2 is a valid CAS Registry Number.

Stereoselective O-Glycosylations by Pyrylium Salt Organocatalysis**

Nielsen, Michael Martin,Holmstr?m, Thomas,Pedersen, Christian Marcus

, (2021/12/30)

Despite many years of invention, the field of carbohydrate chemistry remains rather inaccessible to non-specialists, which limits the scientific impact and reach of the discoveries made in the field. Aiming to increase the availability of stereoselective

Stereoselective β-mannosylations and β-rhamnosylations from glycosyl hemiacetals mediated by lithium iodide

McGarrigle, Eoghan M.,Pepe, Dionissia A.,Pongener, Imlirenla,Ruddy, Joseph J.

, p. 10070 - 10075 (2021/08/04)

Stereoselective β-mannosylation is one of the most challenging problems in the synthesis of oligosaccharides. Herein, a highly selective synthesis of β-mannosides and β-rhamnosides from glycosyl hemi-acetals is reported, following a one-pot chlorination,

Copper-mediated anomeric: O -arylation with organoboron reagents

Dimakos, Victoria,Liu, Jacklyn J. W.,Ge, Zhenlu,Taylor, Mark S.

supporting information, p. 5671 - 5674 (2019/06/18)

Copper-mediated couplings of arylboroxines with glycosyl hemiacetals furnish O-aryl glycosides via Csp2-O bond formation. The method enables the anomeric O-arylation of protected pyranose and furanose derivatives, and is tolerant of functionalized arylboroxine partners. Whereas mixtures of anomers are formed from glucopyranose, galactopyranose and arabinofuranose hemiacetals, the α-anomer is generated selectively from mannopyranose and mannofuranose-derived substrates.
