(E)-2-(2-Phenylselanyl-ethyl)-but-2-enoic acid methyl ester is a complex organic compound with the molecular formula C14H16O2Se. It is characterized by a conjugated diene system, with a methyl ester group attached to the carboxylic acid functionality. The molecule features a phenylselanyl (phenylselenium) group, which is a phenyl ring bonded to a selenium atom, attached to an ethyl chain. This structure endows the compound with unique chemical properties, such as potential reactivity and stability, which can be exploited in various chemical reactions and applications. The "E" configuration in the name indicates the geometric isomerism of the double bond, suggesting that the phenylselanyl group and the methyl ester are on opposite sides of the double bond. (E)-2-(2-Phenylselanyl-ethyl)-but-2-enoic acid methyl ester may be of interest in the fields of organic synthesis, materials science, and potentially as a precursor in the development of pharmaceuticals or specialty chemicals.
The CAS Registry Mumber 70302-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,0 and 2 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 70302-26: (7*7)+(6*0)+(5*3)+(4*0)+(3*2)+(2*2)+(1*6)=80 80 % 10 = 0 So 70302-26-0 is a valid CAS Registry Number.
