Purification Methods
-D-Galactose is crystallised twice from aqueous 80% EtOH at -10o, then dried in a vacuum oven at 90o over P2O5 for 10hours. [Link Biochemical Preparations 3 75 1953, Hansen et al. Biochemical Preparations 4 2 1955.] Also purify it by recrystallising the dried solid (150g) in hot H2O (150mL), then adding hot MeOH (250mL) and hot EtOH (500mL), stirring to mix, filtering through a bed of charcoal, and the clear filtrate is stirred to initiate crystallisation. After standing overnight at 10o, the crystals of the -anomer are filtered off by suction, washed with MeOH, then EtOH, and dried (yield 130g), and more can be obtained by evaporation of the filtrate and washing as before.

Check Digit Verification of cas no
The CAS Registry Mumber 3646-73-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,4 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3646-73:
(6*3)+(5*6)+(4*4)+(3*6)+(2*7)+(1*3)=99
99 % 10 = 9
So 3646-73-9 is a valid CAS Registry Number.

Structural determination of a neutral exopolysaccharide produced by Lactobacillus delbrueckii ssp. bulgaricus LBB.B332
Sanchez-Medina, Inmaculada,Gerwig, Gerrit J.,Urshev, Zoltan L.,Kamerling, Johannis P.

The neutral exopolysaccharide produced by Lactobacillus delbrueckii ssp. bulgaricus LBB.B332 in skimmed milk was found to be composed of d-glucose, d-galactose, and l-rhamnose in a molar ratio of 1:2:2. Linkage analysis and 1D/2D NMR (1H and 13C) studies carried out on the native polysaccharide as well as on an oligosaccharide generated by a periodate oxidation protocol, showed the polysaccharide to consist of linear pentasaccharide repeating units with the following structure:{A figure is presented}.

Seven new acylated iridoid glycosides, picrorhizaosides A–G (1–7), were isolated from the methanol extract of the rhizomes of Picrorhiza kurroa Royle ex Benth. (Plantaginaceae), in addition to six known iridoid glycosides (8–13). The structures of these new iridoids, including their stereochemistry, were determined based on chemical and physicochemical evidence derived from NMR and MS analysis. Of the isolates, picrorhizaosides D (4, IC50 = 43.4 μM) and E (5, 35.8 μM); picrosides I (8, 60.7 μM), II (9, 22.3 μM), and IV (11, 59.2 μM); and minecoside (13, 57.2 μM), exhibited a similar or stronger hyaluronidase inhibitory activity than those of the antiallergic medicines disodium cromoglycate (64.8 μM), ketotifen fumarate (76.5 μM), and tranilast (227 μM).
