57870-03-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57870-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,7 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57870-03:
(7*5)+(6*7)+(5*8)+(4*7)+(3*0)+(2*0)+(1*3)=148
148 % 10 = 8
So 57870-03-8 is a valid CAS Registry Number.

Sequential C-H activation enabled expedient delivery of polyfunctional arenes

Cai, Xiaoqing,Chen, Qian,Chen, Xiaojian,Gao, Yang,Huo, Yanping,Li, Xianwei,Ouyang, Wensen,Rao, Jianhang,Wang, Jie

supporting information, p. 8075 - 8078 (2021/08/20)

Modular construction of polyfunctional arenes from abundant feedstocks stands as an unremitting pursue in synthetic chemistry, accelerating the discovery of drugs and materials. Herein, using the multiple C-H activation strategy with versatile imidate esters, the expedient delivery of molecular libraries of densely functionalized sulfur-containing arenes was achieved, which enabled the concise construction of biologically active molecules, such as Bipenamol.

Rh(III)-Catalyzed [3 + 2] Annulation via C-H Activation: Direct Access to Trifluoromethyl-Substituted Indenamines and Aminoindanes

Chaudhary, Bharatkumar,Auti, Prashant,Shinde, Suchita Dattatray,Yakkala, Prasanna Anjaneyulu,Giri, Deepesh,Sharma, Satyasheel

supporting information, p. 2763 - 2767 (2019/04/30)

The rhodium(III)-catalyzed direct C-H addition and annulation of benzimidates and aldimines with β-(trifluoromethyl)-α,β-unsaturated ketones is described. This protocol provides the facile and efficient formation of various trifluoromethyl-containing inde

Ruthenium (II)-Catalyzed Oxidant-Free Coupling/Cyclization of Benzimidates and Sulfoxonium Ylides to Form Substituted Isoquinolines

Shi, Xinxia,Wang, Rongchao,Zeng, Xiaofei,Zhang, Yilan,Hu, Huiling,Xie, Chunsong,Wang, Min

supporting information, p. 4049 - 4053 (2018/09/21)

A ruthenium-catalyzed direct mono-C?H functionalization/annulation cascade reaction of benzimidates and sulfoxonium ylides has been developed. The reaction proceeds smoothly with a broad range of substrates, giving access to a variety of isoquinoline deri
