628281-92-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 628281-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,8,2,8 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 628281-92:
(8*6)+(7*2)+(6*8)+(5*2)+(4*8)+(3*1)+(2*9)+(1*2)=175
175 % 10 = 5
So 628281-92-5 is a valid CAS Registry Number.

P-Methoxybenzyl-N-phenyl-2,2,2-trifluoroacetimidate: A versatile reagent for mild acid catalyzed etherification

Barroca-Aubry, Nadine,Benchekroun, Mohamed,Gomes, Filipe,Bonnaffé, David

, p. 5118 - 5121 (2013/09/02)

PMB-NPTFA 1a is a new month bench stable and powerful reagent for the formation of PMB ethers. Several alcohols were protected in high yields and short reaction times, using low reagent loading and small catalytic amounts of Bi(OTf)3. The mild

Efficient preparation of three building blocks for the synthesis of heparan sulfate fragments: Towards the combinatorial synthesis of oligosaccharides from hypervariable regions

Gavard, Ollivier,Hersant, Yael,Alais, Jocelyne,Duverger, Veronique,Dilhas, Anna,Bascou, Alison,Bonnaffe, David

, p. 3603 - 3620 (2007/10/03)

New, multigram routes to suitably protected L-iduronyl monosaccharide donors 4 and 5 and 2-azidoglucose acceptors 6 and 7 are described. The L-iduronyl and D-glucuronyl disaccharides 1-3 were then prepared from these compounds, by means of efficient and regioselective protective group manipulations. These disaccharides form the basis of a combinatorial approach toward the synthesis of heparan sulfate fragments representative of the heterogeneous regions of this polysaccharide.
