512-69-6 Usage
Description
Raffinose is also called melitose, melitriose, or gossypose.The term raffinose is derived from the French word raffiner (to refine)，owing to the fact that it was identified first in the products of beet-sugar refining.Raffinose is found in sugar-beets in small quantities and also in cotton seeds.Raffinose is a trisaccharide composed of galactose, fructose, and glucose. It can be found in beans, cabbage, brussels sprouts, broccoli, asparagus, and other plants. In plants, raffinose is generated via binding of galactinol (a sugar alcohol) to sucrose. Raffinose has only 20 % of the sweetening intensity of sucrose.It is much more readily soluble in hot water than sucrose，consequently it remains in syrups and molasses during sugar refining process，especially in those products obtained from the process of extracting sugarfrom molasses.
Uses
D-(+)-Raffinose is an oligosaccharide and trisaccharide whose physical structure and chemical properties have been shown to affect the stability and crystallization of amorphous sucrose, helping to increase the shelf-life of sucrose-containing foods.
Definition
ChEBI: Raffinose is a trisaccharide composed of alpha-D-galactopyranose, alpha-D-glucopyranose and beta-D-fructofuranose joined in sequence by 1->6 and 1<->2 glycosidic linkages, respectively. It has a role as a plant metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. It is a raffinose family oligosaccharide and a trisaccharide.
Check Digit Verification of cas no
The CAS Registry Mumber 512-69-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 512-69:
(5*5)+(4*1)+(3*2)+(2*6)+(1*9)=56
56 % 10 = 6
So 512-69-6 is a valid CAS Registry Number.

A convenient approach for synthesis of raffinose, stachyose, and verbascose using sucrose as the starting material is presented. The key step is the regioselective de-O-benzylation with Co2(CO)8/Et 3SiH/CO system, followed by a high α-selective glycosylation. The newly developed de-O-benzylation system is efficient in removing the primary benzyl groups of sucrose and raffinose under mild condition and with high selectivity. Using thioglycoside as donor, NIS/AgOTf as promoter and DTBMP as additive, glycosylation of acid labile sucrose substrate is achieved in high yield.
