1-(3,4-dichloro-phenyl)-butane-1,2,3-trione 2-oxime, also known as dichloroacetylacetone oxime, is a chemical compound with the molecular formula C10H8Cl2NO3. It is a derivative of butane-1,2,3-trione (acetylacetone), where one of the hydrogen atoms is replaced by a 3,4-dichloro-phenyl group, and the remaining hydrogen atom is replaced by a hydroxyl group to form an oxime. 1-(3,4-dichloro-phenyl)-butane-1,2,3-trione 2-oxime is often used as a reagent in organic synthesis and as a building block for the synthesis of various pharmaceuticals and agrochemicals. It is characterized by its ability to form complexes with metal ions, which can be useful in analytical chemistry for the detection and quantification of certain metals.
The CAS Registry Mumber 6823-19-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,2 and 3 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 6823-19: (6*6)+(5*8)+(4*2)+(3*3)+(2*1)+(1*9)=104 104 % 10 = 4 So 6823-19-4 is a valid CAS Registry Number.
