124662-85-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124662-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,6 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 124662-85:
(8*1)+(7*2)+(6*4)+(5*6)+(4*6)+(3*2)+(2*8)+(1*5)=127
127 % 10 = 7
So 124662-85-7 is a valid CAS Registry Number.

SYNTHESIS OF GALACTOFURANOSE DISACCHARIDES OF BIOLOGICAL SIGNIFICANCE

Marino, Carla,Varela, Oscar,Lederkremer, Rosa M. De

, p. 65 - 76 (1989)

Methyl β-D-galactofuranoside (3) was readily obtained by tin(IV) chloride-catalyzed glycosylation of penta-O-benzoyl-α,β-D-galactofuranose (1), followed by debenzoylation with sodium methoxide.Glycosylation of 1 with 2,3,5-tri-O-benzoyl-D-galactono-1,4-la

Convenient syntheses of 5-O- and 3,5-di-O-(β-D-galactofuranosyl)-D-galactofuranose

Lederkremer, Rosa M. de,Marino, Carla,Varela, Oscar

, p. 227 - 235 (2007/10/02)

Benzoylation of D-galactono-1,4-lactone with 2.2 mol of benzoyl chloride, at -23 deg C, gave the 2,6-dibenzoate (2, 62percent).Tin(IV) chloride-catalyzed glycosylation of 2 with 1,2,3,5,6-penta-O-benzoyl-α,β-D-galactofuranose (1) afforded 2,6-di-O-benzoyl-5-O-(2,3,5,6-tetra-O-benzoyl-β-D-galactofuranosyl)-D-galactono-1,4-lactone (4, 70percent), HO-3 of which was benzoylated to give 5.The structure of 4 was confirmed by its conversion into crystalline β-D-Gal f-(1->5)-D-Gal-ol (8).Reduction of the lactone function of 5 with di-isoamylborane followed by debenzoylation gave β-D-Gal f-(1->5)-D-Gal f (7).A by-product of the condensation of 1 with 2 was characterized as 2,6-di-O-benzoyl-3,5-di-O-(2,3,5,6-tetra-O-benzoyl-β-D-galactofuranosyl)-D-galactono-1,4-lactone (9), which was converted, as for 5, into β-D-Gal f-(1->3)-D-Gal f (13).
