The chemical compound "O3,O5-dimethyl-D-threo-[2]pentosulose-bis-(4-bromo-phenylhydrazone)" is a complex organic molecule with a unique structure. It features a pentosulose sugar backbone, which is a type of sugar with five carbon atoms, with methyl groups attached at the third and fifth carbon positions. The D-threo configuration indicates the specific arrangement of these substituents in space. The compound is further characterized by the presence of two 4-bromo-phenylhydrazone groups, which are attached to the carbonyl groups of the pentosulose, forming hydrazone linkages. The bromine atoms in these groups add to the molecular weight and may influence the compound's reactivity and physical properties. O3,O5-dimethyl-D-threo-[2]pentosulose-bis-(4-bromo-phenylhydrazone) is likely to be of interest in the fields of organic chemistry and biochemistry, potentially for its role in studying sugar derivatives or as a reagent in chemical synthesis.
The CAS Registry Mumber 3254-22-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,5 and 4 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3254-22: (6*3)+(5*2)+(4*5)+(3*4)+(2*2)+(1*2)=66 66 % 10 = 6 So 3254-22-6 is a valid CAS Registry Number.
