General Description
1,3,4,5-tetra-O-acetylhex-2-ulopyranose is a chemical compound that is commonly used in organic synthesis. It is a derivative of hex-2-ulopyranose, a six-carbon sugar molecule, and is characterized by the presence of four acetyl groups (CH3CO-) attached to the hydroxyl (OH) groups on carbons 1, 3, 4, and 5 of the sugar ring. 1,3,4,5-tetra-O-acetylhex-2-ulopyranose is often employed as a building block for the synthesis of more complex carbohydrate derivatives, and it is also used as a precursor for the preparation of other organic molecules. The acetyl groups present in 1,3,4,5-tetra-O-acetylhex-2-ulopyranose play an important role in its reactivity and make it a valuable starting material for the creation of new chemical compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 55221-54-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,2 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55221-54:
(7*5)+(6*5)+(5*2)+(4*2)+(3*1)+(2*5)+(1*4)=100
100 % 10 = 0
So 55221-54-0 is a valid CAS Registry Number.

Synthesis of α-Acyloxynitrones and Reactivity towards Samarium Diiodide
Racine, Emilie,Burchak, Olga N.,Py, Sandrine
, p. 4003 - 4012 (2016)
Upon treatment of fructose-derived nitrone 1 with samarium diiodide, with the aim of inducing its umpolung and coupling with electrophiles, an unexpected β-elimination of the benzyloxy group at C-1 was observed, yielding nitrone 2. The mechanism and scope
