667463-64-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 667463-64-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,7,4,6 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 667463-64:
(8*6)+(7*6)+(6*7)+(5*4)+(4*6)+(3*3)+(2*6)+(1*4)=201
201 % 10 = 1
So 667463-64-1 is a valid CAS Registry Number.

Ru(III)-mediated intramolecular ortho-C(sp2)-H activation/oxidative acylation: One-pot synthesis of isatins from α-hydroxy amides

Wang, Yaoling,Li, Weijian,Cheng, Xu,Zhan, Zhen,Ma, Xiaojun,Guo, Li,Jin, Hui,Wu, Yong

, p. 3193 - 3197 (2016/05/24)

A novel and efficient synthesis of isatins from α-hydroxy amides via ruthenium-mediated aromatic C-H activation is described. The reactions proceeded smoothly under mild conditions and generated the corresponding products in good to excellent yields. This methodology has a broad substrate scope and opens up an interesting and attractive avenue for the application of intramolecular ortho-C-H activation.

IBX-promoted domino reaction of α-hydroxy amides: A facile one-pot synthesis of isatins

Wang, Yaoling,Cheng, Xu,Zhan, Zhen,Ma, Xiaojun,Nie, Ruifang,Hai, Li,Wu, Yong

, p. 2870 - 2874 (2016/01/16)

A novel and temperature-controlled oxidation of α-hydroxy amides in the presence of IBX is described. The divergent one-pot synthesis of isatins and α-formyl amides was achieved in good to excellent yields under metal-free conditions. And these two mild methods can tolerate a variety of functional groups, and are operationally simple.
