473449-32-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 473449-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,4,4 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 473449-32:
(8*4)+(7*7)+(6*3)+(5*4)+(4*4)+(3*9)+(2*3)+(1*2)=170
170 % 10 = 0
So 473449-32-0 is a valid CAS Registry Number.

A highly efficient streamlined chemoenzymatic strategy for total synthesis of four prioritized ganglioside cancer antigens GD2, GD3, fucosyl GM1, and GM3 from commercially available lactose and phytosphingosine is demonstrated. Lactosyl sphingosine (LacβS

Synthesis of a chlorogenin glycoside library using an orthogonal protecting group strategy

Wang, Ying-Hsin,Yeh, Hsien-Wei,Wang, Hsiao-Wen,Yu, Chia-Chun,Guh, Jih-Hwa,Liu, Der-Zen,Liang, Pi-Hui

, p. 118 - 135 (2013/07/27)

Naturally occurring spirostanol saponins bear a chacotriose, α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→4)] -β-d-glucopyranose residue as the oligosaccharide moiety which is believed to be important for biological activity. Herein the development of a concise, combinatorial method for the synthesis of two series of glycan variants at the 2′ and/or 4′ positions of chacotriose is described and the structure-activity relationships of the glycone part at 3-OH of chlorogenin investigated. These compounds were found to be weakly-cytotoxic toward leukemia cell lines CCRF and HL-20, indicating that the chacotriose moiety is important for anticancer activity.

Synthesis of LD-Hepp and KDO containing di- and tetrasaccharide derivatives of Neisseria meningitidis inner-core region via iodonium ion promoted glycosidations
