4H-benzo[1,4]selenazine-2,3-dione 2-ptolylhydrazone is a complex organic compound with the molecular formula C15H12N2O2Se. It is a derivative of benzo[1,4]selenazine-2,3-dione, which is a heterocyclic compound containing selenium. The 2-ptolylhydrazone part of the molecule indicates the presence of a hydrazone functional group attached to the 2-position of the benzene ring, where the p-tolyl group (a methyl-substituted phenyl group) is connected to the nitrogen atom of the hydrazone. 4H-benzo[1,4]selenazine-2,3-dione 2-p-tolylhydrazone is likely to be used in chemical research, particularly in the study of selenium-containing heterocycles and their potential applications in various fields such as pharmaceuticals, materials science, or as intermediates in organic synthesis. The specific properties, reactivity, and applications of 4H-benzo[1,4]selenazine-2,3-dione 2-ptolylhydrazone would depend on its chemical structure and the nature of the substituents present.
The CAS Registry Mumber 3240-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,4 and 0 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3240-05: (6*3)+(5*2)+(4*4)+(3*0)+(2*0)+(1*5)=49 49 % 10 = 9 So 3240-05-9 is a valid CAS Registry Number.
