2-Chlor-cyclotridec-2-en-1-on-<2,4-dinitro-phenylhydrazon> is a complex organic compound with the molecular formula C19H22ClN5O4. It is derived from cyclotridec-2-en-1-on, a 13-carbon cyclic ketone, by the addition of a chlorine atom at the 2-position and a 2,4-dinitrophenylhydrazone group. The 2,4-dinitrophenylhydrazone group is formed by the reaction of the ketone with 2,4-dinitrophenylhydrazine, which is used to form hydrazones with aldehydes and ketones for analytical purposes. 2-Chlor-cyclotridec-2-en-1-on-<2,4-dinitro-phenylhydrazon> is characterized by its unique structure, which includes a cycloalkane ring, a double bond, a chlorine atom, and a 2,4-dinitrophenylhydrazone functional group. It is typically used in chemical research and analysis, particularly in the identification and characterization of ketones due to the distinct color and melting point changes that occur upon formation of the hydrazone derivative.
The CAS Registry Mumber 7777-82-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 7 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 7777-82: (6*7)+(5*7)+(4*7)+(3*7)+(2*8)+(1*2)=144 144 % 10 = 4 So 7777-82-4 is a valid CAS Registry Number.
