Methyl--amidophosphorsaeure-dimethylester, also known as methyl tosyl-amidophosphorodimethylester, is a complex organic compound with the chemical formula C10H14NO5PS. It is a derivative of amidophosphoric acid, featuring a methyl group, a tosyl group (sulfonyl group attached to a toluene ring), and two methyl ester groups. Methyl--amidophosphorsaeure-dimethylester is primarily used as a reagent in organic synthesis, particularly in the formation of amide bonds and as a protecting group for amines. It is known for its ability to facilitate coupling reactions and can be used in the synthesis of various pharmaceuticals and other complex organic molecules. Due to its reactivity and specificity, it plays a significant role in the field of chemical research and development.
The CAS Registry Mumber 3335-59-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,3 and 5 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 3335-59: (6*3)+(5*3)+(4*3)+(3*5)+(2*5)+(1*9)=79 79 % 10 = 9 So 3335-59-9 is a valid CAS Registry Number.
