4-bromo-3-methyl-2-(toluene-4-sulfonyl)-2H-isoxazol-5-one is a complex organic compound with the molecular formula C11H10BrNO4S. It features a 2H-isoxazol-5-one core structure, which is a heterocyclic ring system containing an isoxazole ring fused to a carbonyl group. The compound is characterized by the presence of a bromine atom at the 4-position, a methyl group at the 3-position, and a toluene-4-sulfonyl group attached to the 2-position. The toluene-4-sulfonyl group is a derivative of toluene, where one of the hydrogen atoms on the benzene ring is replaced by a sulfonyl group (-SO2-). This chemical is likely to be used in advanced chemical synthesis, potentially as an intermediate in the production of pharmaceuticals or other specialty chemicals, due to its unique structure and functional groups.
The CAS Registry Mumber 1517-97-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,1 and 7 respectively; the second part has 2 digits, 9 and 7 respectively. Calculate Digit Verification of CAS Registry Number 1517-97: (6*1)+(5*5)+(4*1)+(3*7)+(2*9)+(1*7)=81 81 % 10 = 1 So 1517-97-1 is a valid CAS Registry Number.
