53271-49-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53271-49-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,7 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 53271-49:
(7*5)+(6*3)+(5*2)+(4*7)+(3*1)+(2*4)+(1*9)=111
111 % 10 = 1
So 53271-49-1 is a valid CAS Registry Number.

Controllable phosphorylation of thioesters: Selective synthesis of aryl and benzyl phosphoryl compounds

Xu, Kaiqiang,Liu, Long,Li, Zhaohui,Huang, Tianzeng,Xiang, Kang,Chen, Tieqiao

, p. 14653 - 14663 (2020/12/29)

The controllable phosphorylations of thioesters were developed. When the reaction was catalyzed by a palladium catalyst, aryl or alkenyl phosphoryl compounds were generated through decarbonylative coupling, while the benzyl phosphoryl compounds were produced through deoxygenative coupling when the reaction was carried out in the presence of only a base.

Metal-free thioesterification of amides generating acyl thioesters

Wang, Qun,Liu, Long,Dong, Jianyu,Tian, Zhibin,Chen, Tieqiao

supporting information, p. 9384 - 9388 (2019/06/21)

A base-initiated thioesterification of amides with various thiols is reported. This reaction can take place efficiently under metal-free and air-atmospheric conditions, and provides a facile and practically useful approach to the synthesis of valuable acy
