3-methyl-isoxazole-4,5-dione 4-[(3-chloro-4-methyl-phenyl)-hydrazone] is a complex organic compound with the molecular formula C11H8ClN3O2. It is a derivative of isoxazole-4,5-dione, which is a heterocyclic compound containing an isoxazole ring and a dione group. The molecule features a 3-methyl group attached to the isoxazole ring, and a 4-hydrazone group connected to the dione moiety. The hydrazone group is formed by the reaction of the isoxazole-4,5-dione with a 3-chloro-4-methyl-phenyl hydrazine, resulting in the formation of a new C-N bond. 3-methyl-isoxazole-4,5-dione 4-[(3-chloro-4-methyl-phenyl)-hydrazone] is of interest in the field of organic chemistry and may have potential applications in the synthesis of pharmaceuticals and other chemical products.
The CAS Registry Mumber 1627-12-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 7 respectively; the second part has 2 digits, 1 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1627-12: (6*1)+(5*6)+(4*2)+(3*7)+(2*1)+(1*2)=69 69 % 10 = 9 So 1627-12-9 is a valid CAS Registry Number.
