It is a derivative of hydrindanon, which is a type of hydrazone, formed by the reaction of a hydrazine with an aldehyde or ketone. The compound is specifically named for its cis-configuration, indicating that the two substituents are on the same side of the double bond. The 2,4-dinitro-phenylhydrazone part of the name refers to the presence of a 2,4-dinitrophenyl group attached to the hydrazone, which is a common practice in organic chemistry to modify the properties of the parent compound. cis-Hydrindanon-(5)-<2,4-dinitro-phenylhydrazon> is often used in chemical research and analysis due to its distinct chemical properties and reactivity.
The CAS Registry Mumber 4668-90-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 8 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4668-90: (6*4)+(5*6)+(4*6)+(3*8)+(2*9)+(1*0)=120 120 % 10 = 0 So 4668-90-0 is a valid CAS Registry Number.
