1570134-48-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1570134-48-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,0,1,3 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1570134-48:
(9*1)+(8*5)+(7*7)+(6*0)+(5*1)+(4*3)+(3*4)+(2*4)+(1*8)=143
143 % 10 = 3
So 1570134-48-3 is a valid CAS Registry Number.

Oxazolinyl-Assisted C-H Amidation by Cobalt(III) Catalysis

Mei, Ruhuai,Loup, Joachim,Ackermann, Lutz

, p. 793 - 797 (2016)

Cobalt-catalyzed C-H activation by means of oxazolinyl assistance set the stage for versatile direct amidations with ample substrate scope. Thus, a high-valent cobalt(III) catalyst enabled C-H amidations with excellent levels of positional and chemo-selec

Rhodium(III)-catalyzed chemodivergent annulations between phenyloxazoles and diazos via C–H activation

Zhang, Xueguo,Wang, Peigen,Zhu, Liangwei,Chen, Baohua

, p. 695 - 699 (2020/06/28)

Acid-controlled, chemodivergent and redox-neutral annulations for the synthesis of isocoumarins and isoquinolinones have been realized via Rh(III)-catalyzed C[sbnd]H activation. Diazo compounds act as a carbene precursor, and coupling occurs in one-pot process, where adipic acid and trimethylacetic acid promote chemodivergent cyclizations.

Cu-Catalyzed C-H Alkenylation of Benzoic Acid and Acrylic Acid Derivatives with Vinyl Boronates

Li, Jian-Jun,Wang, Cheng-Gang,Yu, Jin-Feng,Wang, Peng,Wang, Peng,Yu, Jin-Quan

, p. 4692 - 4696 (2020/06/25)

An efficient Cu-catalyzed C-H alkenylation with acyclic and cyclic vinyl boronates was realized for the first time under mild conditions. The scope of the vinyl borons and the compatibility with functional groups including heterocycles are superior than Pd-catalyzed C-H coupling with vinyl borons, providing a reliable access to multisubstituted alkenes and dienes. Subsequent hydrogenation of the product from the internal vinyl borons will lead to installation of secondary alkyls.
