α-Isopropyl-2,3,4,6-tetra-O-acetyl-D-glucopyranoside is a complex organic compound that belongs to the class of carbohydrates, specifically a derivative of D-glucose. This chemical is characterized by the presence of an isopropyl group at the anomeric carbon (C1) and four acetyl groups attached to the hydroxyl groups at the 2, 3, 4, and 6 positions of the glucopyranose ring. The acetyl groups serve to protect the hydroxyl groups, which is a common strategy in organic synthesis to prevent unwanted side reactions. α-isopropyl-2,3,4,6-tetra-O-acetyl-D-glucopyranoside is often used as a substrate in glycosylation reactions, a key process in the synthesis of complex carbohydrates and glycoconjugates. It is also employed in the study of enzyme specificity and as a building block in the preparation of various biologically active molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 20226-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,2 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20226-73:
(7*2)+(6*0)+(5*2)+(4*2)+(3*6)+(2*7)+(1*3)=67
67 % 10 = 7
So 20226-73-7 is a valid CAS Registry Number.

Variations on the SnCl4 and CF3CO2Ag-promoted glycosidation of sugar acetates: a direct, versatile and apparently simple method with either α or β stereocontrol

Xue, Jia Lu,Cecioni, Samy,He, Li,Vidal, Sébastien,Praly, Jean-Pierre

, p. 1646 - 1653 (2009)

Glycosidation of sugar peracetates (d-gluco, d-galacto) with SnCl4 and CF3CO2Ag led to either 1,2-cis-, or 1,2-trans-glycosides, depending primarily on the alcohols used. In particular, 1,2-trans-glycosides, expected from acyl-protected glycosyl donors, were formed in high yields with alcohols sharing specific features such as bulkiness, presence of electron-withdrawing groups or polyethoxy motifs. In contrast, simple alcohols afforded ～1:1 mixtures of 2,3,4,6-tetra-O-acetyl, and 3,4,6-tri-O-acetyl 1,2-cis-glycosides due to anomerization and/or acid-catalyzed fragmentation of 1,2-orthoester intermediates. After reacetylation or deacetylation, acetylated or fully deprotected 1,2-cis-glycosides (α-d-gluco, α-d-galacto) were obtained in ～90% yields by a simple and direct method.
