869639-08-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 869639-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,6,3 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 869639-08:
(8*8)+(7*6)+(6*9)+(5*6)+(4*3)+(3*9)+(2*0)+(1*8)=237
237 % 10 = 7
So 869639-08-7 is a valid CAS Registry Number.

(2-Nitrophenyl)acetyl: A new, selectively removable hydroxyl protecting group

Daragics, Katalin,Fuegedi, Peter

supporting information; experimental part, p. 2076 - 2079 (2010/09/15)

Figure presented The utility of the (2-nitrophenyl)acetyl (NPAc) group for the protection of hydroxyl functions is reported. (2-Nitrophenyl)acetates are readily prepared starting from the commercially available, inexpensive (2-nitrophenyl)acetic acid, and these esters are stable under a series of common carbohydrate transformations. The NPAc group can be removed selectively using Zn and NH4Cl without affecting a series of common protecting groups. This new protecting group is orthogonal with the commonly used tert-butyldimethylsilyl, levulinoyl, 9-fluorenylmethoxycarbonyl, naphthylmethyl, and p-methoxybenzyl groups.

Convenient construction of a variety of glycosidic linkages using a universal glucosyl donor

Sato, Ken-Ichi,Akai, Shoji,Sakai, Koudai,Kojima, Masaru,Murakami, Hideshige,Idoji, Tetsuya

, p. 7411 - 7414 (2007/10/03)

This letter deals with the concept of constructing four types (cis-α, trans-α, cis-β, and trans-β) of glycosidic linkages using a universal glucosyl donor. The selectively protected universal glucosyl donor 8 was synthesized in 36% yield from d-glucose (eight steps). The donor 8 undergoes glycosidation with a primary carbohydrate alcohol 7 to give disaccharide 9 having a 1,2-cis-α-glycosidic linkage in 90% yield. The construction of the corresponding 1,2-trans-α-glycosidic linkage was performed in 68% yield (three steps) from 9. A similar glycosidation of the 2-O-(N- phenylcarbamoyl)-glucosyl donor 6 derived from 8 with 7 gave disaccharide 11 having a 1,2-trans-β-glycosidic linkage in 75% yield. The construction of the corresponding 1,2-cis-β-linkage was performed in 53% yield (three steps) from 11.
