(4-chloro-phenyl)-(tetra-O-acetyl-β-D-galactopyranoside) is a complex organic compound consisting of a 4-chlorophenyl group and a tetra-O-acetyl-β-D-galactopyranoside moiety. The 4-chlorophenyl group is a derivative of benzene with a chlorine atom attached at the para position, while the tetra-O-acetyl-β-D-galactopyranoside is a derivative of β-D-galactopyranose, a monosaccharide, with four acetyl groups attached to its hydroxyl groups. (4-chloro-phenyl)-(tetra-O-acetyl-β-D-galactopyranoside) is significant in the field of organic chemistry and carbohydrate chemistry, as it represents a conjugate of a phenyl group and a protected galactose derivative. Such compounds are often used in the synthesis of more complex molecules, including pharmaceuticals and other bioactive compounds, due to their ability to serve as building blocks or intermediates in chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 2872-70-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,7 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2872-70:
(6*2)+(5*8)+(4*7)+(3*2)+(2*7)+(1*0)=100
100 % 10 = 0
So 2872-70-0 is a valid CAS Registry Number.

Stereoselective single-step synthesis and X-ray crystallographic investigation of acetylated aryl 1,2-trans glycopyranosides and aryl 1,2-cis C2-hydroxy-glycopyranosides

Aich, Udayanath,Loganathan, Duraikkannu

, p. 19 - 28 (2007/10/03)

Reported is an attractive and environmentally friendly method for the synthesis of the title compounds in moderate yield using inexpensive 1,2,3,4,6-penta-O-acetyl-β-d-gluco- and galactopyranoses as sugar donors, five different phenols as acceptors and H-β zeolite as the catalyst. The yield (23-28%) of aryl 3,4,6-tri-O-acetyl-α-d-glycopyranosides obtained in this single-step procedure is considerably higher than that obtained using previously reported methods. Treatment of an orthoacetate, 3,4,6-tri-O-acetyl- [1,2-O-(1-p-fluorophenoxyethylidene)]-α-d-glucopyranose, with p-fluorophenol under the same solvent-free reaction conditions also led to the formation of the title compounds in similar yield and composition. X-ray crystallographic analysis of phenyl 3,4,6-tri-O-acetyl-α-d-glucopyranoside and p-fluorophenyl 3,4,6-tri-O-acetyl-α-d-glucopyranoside showed that the molecular packing is stabilized by C-H...O, C-H...π and C-H...F interactions, in addition to regular hydrogen bonding patterns.
