(1-oxo-3-phenyl-3,6-dihydro-1H-1λ4-[1,2]thiazin-2-yl)-phosphonic acid diethyl ester is a complex organic compound with the molecular formula C16H20NO4PS. It is a derivative of 1,2-thiazine, a heterocyclic compound containing sulfur and nitrogen atoms. This specific compound features a 1-oxo-3-phenyl-3,6-dihydro-1H-1λ4-[1,2]thiazin-2-yl group attached to a phosphonic acid moiety, which is further esterified with two ethyl groups. The compound is characterized by its unique structure, which combines the properties of both the thiazine ring system and the phosphonic acid functionality. It may have potential applications in various fields, such as pharmaceuticals, agrochemicals, or materials science, due to its ability to form stable complexes and its potential reactivity with other molecules. However, further research and characterization would be necessary to fully understand its properties and potential uses.
The CAS Registry Mumber 4921-77-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,2 and 1 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4921-77: (6*4)+(5*9)+(4*2)+(3*1)+(2*7)+(1*7)=101 101 % 10 = 1 So 4921-77-1 is a valid CAS Registry Number.
