1H-Phosphole, 2,5-dihydro-3-methyl-1-phenoxy-, 1-oxide is a complex organic compound with the chemical formula C11H13O2P. It is a derivative of phosphole, a heterocyclic compound containing a phosphorus atom in a five-membered ring. The molecule features a 2,5-dihydro structure, which means it has two hydrogen atoms attached to the carbon atoms at positions 2 and 5. Additionally, it has a methyl group (-CH3) at the 3-position and a phenoxy group (C6H5O-) attached to the 1-position. The 1-oxide functional group indicates the presence of an oxygen atom bonded to the phosphorus atom, which is part of the phosphole ring. 1H-Phosphole, 2,5-dihydro-3-methyl-1-phenoxy-, 1-oxide is of interest in organic chemistry and materials science due to its unique structure and potential applications in the development of new materials and pharmaceuticals.
The CAS Registry Mumber 2921-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,2 and 1 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2921-71: (6*2)+(5*9)+(4*2)+(3*1)+(2*7)+(1*1)=83 83 % 10 = 3 So 2921-71-3 is a valid CAS Registry Number.
