Benzoic acid, 4-(methylseleno)-, ethyl ester, also known as ethyl 4-(methylseleno)benzoate, is an organoselenium compound with the chemical formula C9H10O2Se. It is a colorless to pale yellow liquid with a molecular weight of 221.13 g/mol. Benzoic acid, 4-(methylseleno)-, ethyl ester is characterized by the presence of a benzoic acid moiety, where one of the hydrogen atoms on the benzene ring is replaced by a methylseleno group (-CH2SeH). The ethyl ester functional group is attached to the carboxylic acid group of the benzoic acid, forming an ester linkage. Ethyl 4-(methylseleno)benzoate is an important intermediate in the synthesis of various organoselenium compounds and has potential applications in the pharmaceutical and agrochemical industries due to its unique chemical properties and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 3757-99-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,5 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3757-99:
(6*3)+(5*7)+(4*5)+(3*7)+(2*9)+(1*9)=121
121 % 10 = 1
So 3757-99-1 is a valid CAS Registry Number.

Aryl Arylazo Sulfones Chemistry. 2. Reactivity toward Alkaline Alkane- and Areneselenolate and Alkane- and Arenetellurolate Anions

Evers, Michel J.,Christiaens, Leon E.,Renson, Marcel J.

, p. 5196 - 5198 (2007/10/02)

Tolyl arylazo sulfones react with various alkyl- and arylseleno reagents to produce substituted alkyl aryl and unsymmetrical diaryl selenides.The corresponding tellurides can also be obtained.Isolated yields in both cases are good.This procedure is an interesting alternative to the classical Sandmeyer reaction.
