16664-48-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16664-48-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,6 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16664-48:
(7*1)+(6*6)+(5*6)+(4*6)+(3*4)+(2*4)+(1*8)=125
125 % 10 = 5
So 16664-48-5 is a valid CAS Registry Number.

Metal-Free Synthesis of Highly Substituted Pyridines by Formal [2+2+2] Cycloaddition under Mild Conditions

Xie, Lan-Gui,Shaaban, Saad,Chen, Xiangyu,Maulide, Nuno

supporting information, p. 12864 - 12867 (2016/10/04)

The synthesis of pyridines through direct intermolecular cycloaddition of alkynes and nitriles is a contemporary challenge in organic synthesis. A Br?nsted acid mediated formal [2+2+2] cycloaddition of heteroalkynes and nitriles was developed that proceed

An unprecedented tandem annulation of ω-azido-1-alkynes with diaryl-iodonium salts: A facile synthesis of polycyclic quinolines

Chen, Junjie,Chen, Chao,Chen, Jing,Gao, Hongpeng,Qu, Hongmei

supporting information, p. 2721 - 2726 (2015/01/08)

Polysubstituted quinolines are synthesized through an unprecedented cascade annulation of ω-azido-1-alkynes with diaryliodonium salts, which serve as C2-building blocks. The reaction proceeds smoothly and is catalyzed by Cu(I) catalysts to give various qu
