1493-43-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1493-43-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,9 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1493-43:
(6*1)+(5*4)+(4*9)+(3*3)+(2*4)+(1*3)=82
82 % 10 = 2
So 1493-43-2 is a valid CAS Registry Number.

Cu-Catalyzed Aerobic Oxidative Sulfuration/Annulation Approach to Thiazoles via Multiple Csp3-H Bond Cleavage

Wang, Xiaoyang,Qiu, Xu,Wei, Jialiang,Liu, Jianzhong,Song, Song,Wang, Wen,Jiao, Ning

supporting information, p. 2632 - 2636 (2018/05/22)

A novel and practical Cu-catalyzed aerobic oxidative synthesis of thiazoles was developed. This chemistry for the first time achieved thiazole construction from simple aldehydes, amines, and element sulfur through multiple Csp3-H bond cleavage processes. Molecular oxygen was used as a green oxidant in this oxidative protocol. The substrate scope is broad with the tolerance of aliphatic amines. The mechanistic study might promote the reaction design for a new sulfuration/annulation reaction with readily available element sulfur.
