(2R,3R,4S,5R,6S)-2-(acetoxymethyl)-6-(2-cyanophenoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate is a complex organic compound with a molecular formula of C20H23NO9. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry, with the R and S configurations at various carbon centers. (2R,3R,4S,5R,6S)-2-(acetoxymethyl)-6-(2-cyanophenoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate features a tetrahydro-2H-pyran ring, which is a type of cyclic ether, and is substituted with an acetoxymethyl group at the 2-position, a 2-cyanophenoxy group at the 6-position, and three acetate groups at the 3, 4, and 5 positions. The presence of the cyano group and the acetate groups contributes to its reactivity and potential applications in chemical synthesis. (2R,3R,4S,5R,6S)-2-(acetoxymethyl)-6-(2-cyanophenoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate is likely to be found in research settings, particularly in the fields of organic chemistry and pharmaceuticals, where its unique structure may offer specific properties or reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 3444-05-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3444-05:
(6*3)+(5*4)+(4*4)+(3*4)+(2*0)+(1*5)=71
71 % 10 = 1
So 3444-05-1 is a valid CAS Registry Number.

Application of halide molten salts as novel reaction media for O-glycosidic bond formation

Kumar, Vineet,Talisman, Ian Jamie,Malhotra, Sanjay V.

supporting information; experimental part, p. 3377 - 3381 (2010/08/19)

In this study we have explored the application of halide molten salts as reaction media for O-glycosidic bond formation under basic conditions and mild heating. Eighteen different room-temperature ionic liquids and molten salts, representing four different classes of cations (i.e. imidazolium, pyridinium, pyrrolidinium and ammonium), were screened in the glycosidation reaction of p-nitrophenol with aceto-bromo-α-D-galactose. 1-Butyl-4-methylimidazolium chloride (BMIM·Cl) gave the best results and was applied in the reactions of other phenolic substrates to give the products with up to 80% yields. All the reactions were highly selective to give the β-anomers, and the molten salt BMIM·Cl could easily be reused with no apparent loss in activity.
