2,5-Dioxo-pent-3-ensaeure-aethylester-bis-<2,4-dinitrophenylhydrazon> is a complex organic compound with the chemical formula C11H10N6O6. It is derived from 2,5-dioxopent-3-enoic acid, an unsaturated dicarboxylic acid, and is characterized by the presence of two 2,4-dinitrophenylhydrazone groups. These hydrazone groups are formed by the reaction of the carbonyl groups in the dioxopent-3-enoic acid with 2,4-dinitrophenylhydrazine, a common reagent used in organic chemistry for the formation of hydrazones. The compound is of interest in chemical research due to its unique structure and potential applications in the synthesis of other complex organic molecules. It is typically used as an analytical reagent or in the study of chemical reactions involving carbonyl compounds.
The CAS Registry Mumber 5904-73-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,0 and 4 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5904-73: (6*5)+(5*9)+(4*0)+(3*4)+(2*7)+(1*3)=104 104 % 10 = 4 So 5904-73-4 is a valid CAS Registry Number.
