Tri-O-acetyl-aldehydo-keto-DL-threo-[2]pentosulose-bis-phenylhydrazone is a complex organic compound with the molecular formula C23H27N4O7. It is derived from the pentosulose sugar, which is a type of sugar alcohol, and is characterized by the presence of an aldehyde and ketone functional group. The compound is further modified by the addition of three acetyl groups (-COCH3) and two phenylhydrazone moieties, which are formed by the reaction of the aldehyde and ketone groups with phenylhydrazine. This results in a highly conjugated system, which can influence the compound's reactivity and physical properties. The DL-threo configuration indicates that the compound has a specific arrangement of atoms in space, which is important for its stereochemistry. tri-O-acetyl-aldehydo-keto-DL-threo-[2]pentosulose-bis-phenylhydrazone is of interest in organic chemistry and may have applications in the synthesis of more complex molecules or as a research tool in studying sugar chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 4092-28-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,9 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4092-28:
(6*4)+(5*0)+(4*9)+(3*2)+(2*2)+(1*8)=78
78 % 10 = 8
So 4092-28-8 is a valid CAS Registry Number.
