α-(3β)-cholest-5-en-3-yl-2,3,4,6-tetra-O-acetyl-D-glucopyranoside is a complex organic compound that belongs to the class of steroids. It is a derivative of cholesterol, with a cholest-5-en-3-yl group as its core structure. α-(3β)-cholest-5-en-3-yl-2,3,4,6-tetra-O-acetyl-D-glucopyranoside is characterized by the presence of a D-glucopyranoside moiety, which is a sugar molecule, specifically a derivative of glucose. The tetra-O-acetyl group indicates that four hydroxyl groups in the glucose molecule are each acetylated, meaning they are esterified with acetic acid. This acetylated form is often used in chemical synthesis to protect the hydroxyl groups from unwanted reactions until they are needed. The compound is significant in the field of organic chemistry, particularly in the synthesis of complex molecules and the study of steroidal compounds. It serves as an intermediate in the preparation of various biologically active molecules and can be used to explore the structure-activity relationships of steroidal glycosides.

Check Digit Verification of cas no

The CAS Registry Mumber 28154-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,5 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28154-13:
(7*2)+(6*8)+(5*1)+(4*5)+(3*4)+(2*1)+(1*3)=104
104 % 10 = 4
So 28154-13-4 is a valid CAS Registry Number.

THERMAL GLYCOSIDATION WITH BENZYLATED GLYCOSYL CHLORIDES: A VERY SIMPLE PROCEDURE FOR O-GLYCOSIDATION

Nishizawa, Mugio,Kan, Yukiko,Yamada, Hidetoshi

, p. 565 - 567 (2007/10/02)

Thermal condensation of benzylated glucosyl chlorides with a variety of alcohols has been achieved efficiently without using any metal salts via a simple operation, and the procedure is used not only for a glucosyl halide, but also for a xylosyl chloride. KEYWORDS O-glycosidation; thermal glycosidation; glucosyl chloride; xylosyl chloride; disaccharide

SYNTHESIS OF TRITERPENE AND STEROID GLYCOSIDES

Uvarova, Nina I.,Atopkina, Lyubov N.,Elyakov, Georgi B.

, p. 33 - 42 (2007/10/02)

The glycosylation of cholesterol, β-sitosterol, 28-O-acetylbetulin, and betulin with acylated glycosyl halides in the presence of Hg(OAc)2, Hg(CN)2, CdCO3, Ag2O, Ag2CO3, and HgO + HgBr2 usually gives acylated αβ-glycosides accompanied by acetates, ethers, and bromo and unsaturated derivatives of the initial alcohols.The use of Hg(CN)2 gave mainly β anomers (40-87percent), whereas α anomers preponderated when Hg(OAc)2 was the catalyst.When there was a deficiency of hydrogen halide acceptor and in the presence of the acidic catalyst HgBr2*HBr, the β anomer, produced initially, underwent anomerisation.Cholesteryl α-D-glucopyranoside tetra-acetate (48percent) was obtained by anomerisation of the β anomer.
