2-(2-chloro-ethoxy)-5-methyl-3-phenyl-2,3-dihydro-[1,2]oxaphosphole 2-oxide is a complex organic compound with the molecular formula C11H14ClO2PS. It is a derivative of the [1,2]oxaphosphole class of compounds, which are heterocyclic compounds containing a phosphorus atom and an oxygen atom in a six-membered ring. This specific compound features a 2-chloroethoxy group at the 2-position, a methyl group at the 5-position, and a phenyl group at the 3-position. The 2-oxide notation indicates that the compound has an additional oxygen atom incorporated into the structure, which can affect its reactivity and properties. 2-(2-chloro-ethoxy)-5-methyl-3-phenyl-2,3-dihydro-[1,2]oxaphosphole 2-oxide may have potential applications in the fields of pharmaceuticals, agrochemicals, or materials science, but its specific uses and properties would require further investigation and characterization.
The CAS Registry Mumber 5578-03-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,7 and 8 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5578-03: (6*5)+(5*5)+(4*7)+(3*8)+(2*0)+(1*3)=110 110 % 10 = 0 So 5578-03-0 is a valid CAS Registry Number.
