1005004-04-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1005004-04-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,5,0,0 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1005004-04:
(9*1)+(8*0)+(7*0)+(6*5)+(5*0)+(4*0)+(3*4)+(2*0)+(1*4)=55
55 % 10 = 5
So 1005004-04-5 is a valid CAS Registry Number.

First synthesis of 4a-carba-β-d-galactofuranose

Frigell, Jens,Cumpstey, Ian

, p. 9073 - 9076 (2007)

The synthesis of 4a-carba-β-d-galactofuranose is described starting from diacetone glucose. The key ring-closure step was carried out by metathesis to form a cyclopentene. Catalytic hydrogenation of the C{double bond, long}C double bond gave the galacto configured saturated carbahexofuranose with excellent diastereoselectivity.

Carbasugar analogues of galactofuranosides: β-O-linked derivatives and towards β-S-linked derivatives

Frigell, Jens,Eriksson, Lars,Cumpstey, Ian

experimental part, p. 1277 - 1290 (2011/07/09)

A selectively protected carbasugar analogue of β-galactofuranose was synthesised from glucose using ring-closing metathesis as the key step. The carbasugar was converted into an α-galacto configured 1,2-epoxide, which was an effective electrophile in Lewis acid catalysed coupling reactions with alcohols. The epoxide was opened with regioselective attack at C-1 to give β-galacto configured C-1 ethers. Using carbohydrates as nucleophiles, we synthesised a number of pseudodisaccharides. The epoxide was also regioselectively opened at C-1 with a sulfur nucleophile under basic conditions to give a β-galacto configured C-1 thioether.
