13554-85-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13554-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,5 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13554-85:
(7*1)+(6*3)+(5*5)+(4*5)+(3*4)+(2*8)+(1*5)=103
103 % 10 = 3
So 13554-85-3 is a valid CAS Registry Number.

A Flavonol-diglycoside from Melastoma melabathricum

Dinda, B.,Saha, M. K.

, p. 209 - 211 (2007/10/02)

A new flavonol-diglycoside was isolated from the methanolic extract of the aerial parts of Melastoma melabathricum.Its structure was established as quercetin-3-O-α-L-rhamnosyl-(1->2)-β-D-galactoside on the basis of physical and chemical evidences.

ACETOLYSIS OF Leukonostoc mesenteroides NRRL B-1299 DEXTRAN. ISOLATION AND CHARACTERIZATION OF OLIGOSACCHARIDES CONTAINING SECONDARY LINKAGES FROM THE BORATE-SOLUBLE FRACTION

Watanabe, Toshiyuki,Chiba, Michiko,Matsuda, Yutaka,Sakurai, Fukuko,Kobayashi, Mikihiko,Matsuda, Kazuo

, p. 119 - 128 (2007/10/02)

Fractionation of the deacetylated acetolyzate of the borate-soluble fraction of the dextran elaborated by Leuconostoc mesenteroides MRRL B-1299 gave, after chromatography on charcoal-Celite, preparative paper-chromatography, and paper electrophoresis, four trisaccharide fractions and four tetrasaccharide fractions.The isolated oligosaccharides were characterized by their paper-chromatographic mobility, examination of partial acid-hydrolyzates of the oligosaccharides and their corresponding alditols, and methylation analysis.These oligosaccharides were shown to be (a) kojitriose (1), (b) isomaltotriose (2), (c) a mixture of 2-O-α-isomaltosyl-D-glucose (3), 21-O-α-D-glucosylisomaltose (4), and 2-O-α-nigerosyl-D-glucose (5), (d) 6-O-α-kojibiosyl-D-glucose (6), (e) isomaltotetraose (7), (f) a mixture of 2-O-α-isomaltotriosyl-D-glucose (8) and 21-O-α-D-glycosylisomaltotriose (9), (g) 6-O-α-kojitriosyl-D-glucose (10), and (h) 63-O-α-D-glucosylkojitriose (11), respectively.Some of these oligosaccharides are newly isolated and characterized.
