82703-90-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82703-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,0 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82703-90:
(7*8)+(6*2)+(5*7)+(4*0)+(3*3)+(2*9)+(1*0)=130
130 % 10 = 0
So 82703-90-0 is a valid CAS Registry Number.

SYNTHESIS OF 6-O-(5-ACETAMIDO-3,5-DIDEOXY-α-D-glycero-D-galacto-2-NONULOPYRANOSYLONIC ACID)-D-GALACTOSE

Vleugel, Dominicus J. M. van der,Wassenburg, Fred R.,Zwikker, Jan W.,Vliegenthart, Johannes F. G.

, p. 221 - 234 (2007/10/02)

Condensation of methyl 5-acetamido-4,7,8,9-tetra-O-acetyl-2-chloro-2,3,5-trideoxy-β-D-glycero-D-galacto-2-nonulopyranosonate with benzyl 2,3,4-tri-O-benzyl-β-D-galactopyranoside, using silver salicylate as promoter, gave benzyl 2,3,4-tri-O-benzyl-6-O-(methyl-5-acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-α-D-glycero-D-galacto-2-nonulopyranosylonate)-β-D-galactopyranoside (11) as the main product in 65percent yield.Furthermore, the following by-products were formed: methyl 5-acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-2-O-salicyloyl-D-glycero-D-galacto-2-nonulopyranosonate, methyl 5-acetamido-4,7,8,9-tetra-O-acetyl-2,6-anhydro-3,5-dideoxy-D-glycero-D-galacto-non-2-enopyranosonate, and an impure compound that gave, after O-deacetylation and catalytic hydrogenolysis, 6-O-(methyl 5-acetamido-3,5-dideoxy-β-D-glycero-D-galacto-2-nonulopyranosylonate)-D-galactose.O-Deacetylation of 11 gave benzyl 2,3,4-tri-O-benzyl-6-O-(methyl 5-acetamido-3,5-dideoxy-α-D-glycro-D-galacto-2-nonulopyranosylonate)-β-D-galactopyranoside, which was converted into 6-O-(methyl 5-acetamido-3,5-dideoxy-α-D-glycero-D-galacto-2-nonulopyranosylonate)-D-galactose (13) by catalytic hydrogenolysis.Saponification of 13 gave the title compound as its potassium salt.
