2,3,4,5-tetra-O-acetyl-L-arabinose benzoylhydrazone is a complex organic compound derived from L-arabinose, a naturally occurring pentose sugar. 2,3,4,5-tetra-O-acetyl-L-arabinose benzoylhydrazone is characterized by the presence of four acetyl groups (-COCH3) attached to the hydroxyl groups at the 2, 3, 4, and 5 positions of the arabinose molecule, as well as a benzoylhydrazone group (-NHNHCOPh) at the aldehyde group of the sugar. The acetyl groups protect the hydroxyl groups, making the molecule more stable and less reactive, while the benzoylhydrazone group is a derivative of the aldehyde group, which can be used for further chemical reactions or as a protecting group. 2,3,4,5-tetra-O-acetyl-L-arabinose benzoylhydrazone is often used in organic synthesis, particularly in the preparation of various arabinose derivatives, and can be employed in the study of carbohydrate chemistry and the development of new drugs targeting carbohydrate-binding proteins.

Check Digit Verification of cas no

The CAS Registry Mumber 5151-92-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,5 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5151-92:
(6*5)+(5*1)+(4*5)+(3*1)+(2*9)+(1*2)=78
78 % 10 = 8
So 5151-92-8 is a valid CAS Registry Number.

STEREOCHEMICAL ASPECTS OF THE FORMATION OF DIASTEREOISOMERIC 3-ACETYL-2-(POLYACETOXYALKYL)-5-PHENYL-2,3-DIHYDRO-1,3,4-OXADIAZOLES

Somogyi, Laszlo

, p. 19 - 30 (1988)

The synthesis of D- and L-3-acetyl-2-- and 3-acetyl-2--5-phenyl-2,3-dihydro-1,3,4-oxadiazoles via cyclisation of the corresponding (O-acetylating conditions is described.The stereochemical aspects of the formation of C-2 epimeric oxadiazolines are discussed on the basis of optical rotation and n.m.r. data.The acetylation of methylglyoxal bis(benzoylhydrazone) (8) was found to give diastereoisomeric 1,3,4-oxadiazolines (12a and 12b) insteadof the bis(acetylbenzoylhydrazone) 9 claimed in the literature.
