"6-Oxa-2,4-dithia-3-arsaoctanethioic acid, 3-phenyl-5-thioxo, O-ethyl ester" is a complex organic compound with the chemical formula C16H19AsO4S3. It features a unique structure that includes an arsenic atom, two sulfur atoms, and an oxygen atom in its backbone. The molecule is characterized by a 6-oxa (oxygen-containing) ring, a dithia (two sulfur atoms) bridge, and an octanethioic acid (an 8-carbon chain with a thiol group). The 3-phenyl group provides a benzene ring attached to the third carbon, and the 5-thioxo indicates a thiocarbonyl group (a carbonyl group with a sulfur atom) at the fifth position. The O-ethyl ester signifies that an ethyl group is attached to the oxygen atom of the thiol group, forming an ester linkage. 6-Oxa-2,4-dithia-3-arsaoctanethioic acid, 3-phenyl-5-thioxo-, O-ethyl
ester is likely to be of interest in chemical research due to its unusual structure and potential applications in various fields, such as pharmaceuticals or materials science.
The CAS Registry Mumber 2445-11-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,4 and 5 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2445-11: (6*2)+(5*4)+(4*4)+(3*5)+(2*1)+(1*1)=66 66 % 10 = 6 So 2445-11-6 is a valid CAS Registry Number.
