"5-methoxy-6,9-dimethyl-2,3-diphenyl-1,4-dioxa-6,9-diaza-5λ5-phospha-spiro[4.4]non-2-ene" is a complex organic compound with a unique structure. It features a spiro[4.4]non-2-ene framework, which is a nine-membered ring system with a phosphorus atom at the center. The molecule is characterized by the presence of a 1,4-dioxane ring and a 6,9-diaza ring, which contribute to its stability and reactivity. The 5-methoxy group provides an oxygen atom connected to a methyl group, while the 6,9-dimethyl groups add to the steric hindrance and electronic properties of the molecule. The 2,3-diphenyl substituents are phenyl rings attached to the second and third carbon atoms of the spiro ring, enhancing the aromatic character and potentially influencing the compound's physical properties. 5-methoxy-6,9-dimethyl-2,3-diphenyl-1,4-dioxa-6,9-diaza-5λ5-phospha-spiro[4.4]non-2-ene is of interest in the field of organophosphorus chemistry due to its potential applications in areas such as catalysis and material science.
The CAS Registry Mumber 7193-99-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,9 and 3 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 7193-99: (6*7)+(5*1)+(4*9)+(3*3)+(2*9)+(1*9)=119 119 % 10 = 9 So 7193-99-9 is a valid CAS Registry Number.
