5-O-acetyl-1,2-O-isopropylidene-β-L-idofuranurono-6,3-lactone is a complex organic compound with the molecular formula C12H16O7. It is a derivative of β-L-idofuranurono-6,3-lactone, a sugar acid that is a component of certain polysaccharides. The compound is characterized by the presence of an acetyl group (5-O-acetyl) and an isopropylidene group (1,2-O-isopropylidene), which are functional groups that contribute to its chemical properties. The acetyl group is an ester derived from acetic acid, while the isopropylidene group is a protecting group used in organic synthesis to prevent certain reactions from occurring at specific sites. 5-O-acetyl-1,2-O-isopropylidene-β-L-idofuranurono-6,3-lactone is of interest in the field of carbohydrate chemistry and may have applications in the synthesis of complex carbohydrates and related compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 5206-40-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5206-40:
(6*5)+(5*2)+(4*0)+(3*6)+(2*4)+(1*0)=66
66 % 10 = 6
So 5206-40-6 is a valid CAS Registry Number.

DETERMINATION DES SITES D'OXYDATION DES DERIVES DU α-D-GLUCOFURANOSE UTILISES COMME DONNEURS

Descotes, Gerard,Sinou, Denis,Praly, Jean-Pierre

, p. 25 - 32 (2007/10/02)

The sites of oxidation, by catalytic transfer of H, of derivatives of 1,2-O-isopropylidene-α-D-glucofuranose suggest a regiospecific reaction.Compounds having vicinal hydroxyl groups at C-5 and C-6, or at C-3 and C-5, are oxidized at OH-5, whereas compounds having two hydroxyl groups at C-3 and C-6 or three hydroxyl groups give first aldehydes and then lactones.
