Check Digit Verification of cas no

The CAS Registry Mumber 86783-82-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,7,8 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 86783-82:
(7*8)+(6*6)+(5*7)+(4*8)+(3*3)+(2*8)+(1*2)=186
186 % 10 = 6
So 86783-82-6 is a valid CAS Registry Number.

REACTIONS OF GLYCALS WITH XENON FLUORIDE: AN IMPROVED SYNTHESIS OF 2-DEOXY-2-FLUOROSACCHARIDES

Korytnyk, W.,Valentekovic-Horvat, S.

, p. 1493 - 1496 (1980)

The 1,2-double bond in acetylated glycals has been fluorinated with XeF2 in the presence of BF3 to give 1,2-deoxy-1,2-difluorosaccharides.A mechanism for this reaction has been proposed.This method represents an improvement in the synthesis of 2-deoxy-2-fluorosaccharides.

Anomeric Selectivity of Trehalose Transferase with Rare l -Sugars

Bento, Isabel,Hagedoorn, Peter-Leon,Hanefeld, Ulf,Jeffries, Cy M.,Laustsen, Jesper U.,Marsden, Stefan R.,Mestrom, Luuk,Svergun, Dmitri I.,Van Der Eijk, Hessel

, p. 8835 - 8839 (2020/09/18)

Retaining LeLoir glycosyltransferases catalyze the formation of glycosidic bonds between nucleotide sugar donors and carbohydrate acceptors. The anomeric selectivity of trehalose transferase from Thermoproteus uzoniensis was investigated for both d- and l-glycopyranose acceptors. The enzyme couples a wide range of carbohydrates, yielding trehalose analogues with conversion and enantioselectivity of >98%. The anomeric selectivity inverts from α,α-(1 → 1)-glycosidic bonds for d-glycopyranose acceptors to α,β-(1 → 1)-glycosidic bonds for l-glycopyranose acceptors, while (S)-selectivity was retained for both types of sugar acceptors. Comparison of protein crystal structures of trehalose transferase in complex with α,α-trehalose and an unnatural α,β-trehalose analogue highlighted the mechanistic rationale for the observed inversion of anomeric selectivity.

Solid-supported reagents composed of a copolymer possessing 2-O-sulfonyl mannosides and phase-transfer catalysts for the synthesis of 2-fluoroglucose

Takeuchi, Ryota,Sakai, Yuki,Tanaka, Hiroshi,Takahashi, Takashi

supporting information, p. 5500 - 5503 (2015/11/18)

We described the synthesis of a solid-supported co-polymer possessing mannosides and phase-transfer catalysts and synthesis of 2-fluoroglucoside from it. We first prepared a soluble copolymer from two allene monomers possessing a precursor for the synthesis of 2-fluoroglycose and a crown ether. The copolymerization of the monomers via the π-ally nickel-catalyst smoothly proceeded at room temperature to provide a desired copolymer without decomposition of the sulfonate esters. The copolymer exhibited high reactivity towards fluorination in comparison with a conventional precursor. We next synthesized the solid-supported copolymer by using the solid-supported initiator attached with TentaGel resins. TentaGel enabled polymerization under stirring with stirring bar without decomposition. The solid-supported copolymer exhibited comparable reactivity towards fluorination in comparison with the soluble copolymer. In addition, it can be easily separated from the reaction vessel by filtration.
