Check Digit Verification of cas no

The CAS Registry Mumber 143249-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,4 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143249-53:
(8*1)+(7*4)+(6*3)+(5*2)+(4*4)+(3*9)+(2*5)+(1*3)=120
120 % 10 = 0
So 143249-53-0 is a valid CAS Registry Number.

Hydroxymethyl rotamer populations in disaccharides

Roen, Alfredo,Padron, Juan I.,Vazquez, Jesus T.

, p. 4615 - 4630 (2003)

Sixteen methyl glucopyranosyl glucopyranoside disaccharides (methyl β-D-Glcp(p-Br-Bz)-(1→x)-β/ α-D-Glcp) containing β-glycosidic linkages (1→2, 1→3, 1→4, and 1→6) were synthesized and analyzed by means of CD and NMR spectroscopy in three different solvent

Tandem epoxidation-alcoholysis or epoxidation-hydrolysis of glycals catalyzed by titanium(IV) isopropoxide or Venturello's phosphotungstate complex

Levecque, Pieter,Gammon, David W.,Kinfe, Henok Hadgu,Jacobs, Pierre,De Vos, Dirk,Sels, Bert

body text, p. 1557 - 1568 (2009/07/10)

Venturello's phosphotungstate complex and titanium(IV) isopropoxide [Ti(O-i-Pr)4] were successfully used as catalysts for the epoxidation-alcoholysis of glycals using hydrogen peroxide [H2O 2]. Reaction substrates included a range of variously protected glycals and different alcohols were used as solvents. Ti(O-i-Pr)4 was only effective in methanol as solvent, but gave methyl glycosides in high yields and high selectivities. The Venturello complex proved to be a very versatile and efficient catalyst. Apart from epoxidation-alcoholysis in alcoholic solvents it also showed activity in biphasic conditions to allow for glycosylation of long-chain alcohols and was very effective in the stereoselective dihydroxylation of benzylated glucal.

Binding studies on internal immunodeterminants: synthesis of β-(1->6)-linked oligosaccharide methyl glycosides having one to four internal D-galactopyranosyl residues flanked by gentiobiose residues

Ziegler, Thomas,Sutoris, Heinz,Glaudemans, Cornelis P. J.

, p. 271 - 292 (2007/10/02)

The oligosaccharide glycosides β-D-Glcp-(1->6)-β-D-Glcp-(1->6)-6)>n-β-D-Glcp-(1->6)-β-D-Glcp-1->OMe (n=1-4) were prepared by a convergent block synthesis.Haloacetyl, tert-butyldiphenylsilyl, and dimethylthexylsilyl groups were used as tempo
