123765-17-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123765-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,6 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123765-17:
(8*1)+(7*2)+(6*3)+(5*7)+(4*6)+(3*5)+(2*1)+(1*7)=123
123 % 10 = 3
So 123765-17-3 is a valid CAS Registry Number.

A NEW APPROACH TO THE SYNTHESIS OF DISACCHARIDE DERIVATIVES HAVING A FURANOSE AS THE REDUCING UNIT

Mortier, Cecile Du,Varela, Oscar,Lederkremer, Rosa M. De

, p. 79 - 86 (2007/10/02)

The lactonic disaccharide 2,3,5-tri-O-benzoyl-6-O-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-D-galactono-1,4-lactone (7) was prepared by condensing 6-O-trityl-2,3,5-tri-O-benzoyl-D-galactono-1,4-lactone (2) with 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide (4) or with 1,2,3,4,6-penta-O-acetyl-β-D-glucopyranose (6).The reaction was carried out using various catalysts.In the presence of silver trifluoromethanesulfonate or tin(IV) chloride, formation of the 1,2-trans glycosidic bond took place stereoselectively, to afford compound 7 in good yields.However, condensation of 2,3,5-tri-O-benzoyl-D-galactono-1,4-lactone (3) with 4 catalyzed by mercuric salts gave 3,4,6-tri-O-acetyl-1,2-O--α-D-glucopyranose (5) as the main product.Reduction of the lactone function of 7 with bis(3-methyl-2-butyl)borane led to 2,3,5-tri-O-benzoyl-6-O-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-β-D-galactofuranose (8).
