1217189-15-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1217189-15-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,1,8 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1217189-15:
(9*1)+(8*2)+(7*1)+(6*7)+(5*1)+(4*8)+(3*9)+(2*1)+(1*5)=145
145 % 10 = 5
So 1217189-15-5 is a valid CAS Registry Number.

Copper-catalyzed aromatic C-H bond halogenation with lithium halides under aerobic conditions

Mo, Song,Zhu, Yamin,Shen, Zengming

, p. 2756 - 2760 (2013/05/08)

A concise and practical Cu-catalyzed protocol for the preparation of chloro- and bromoarenes via C-H bond activation has been developed. The advantages of this strategy are the employment of cheap Cu(NO3) 2·3H2O, LiX and O2, and its compatibility with both electron-donating and electron-withdrawing substituents on aryl rings.

Direct synthesis of ortho-dihalogenated arylpyrimidines using calcium halides as halogen sources

Zheng, Xiaojian,Song, Bingrui,Li, Guifei,Liu, Bingxin,Deng, Hongmei,Xu, Bin

supporting information; experimental part, p. 6641 - 6645 (2011/02/21)

Pyrimidines and their derivatives have been used as important motifs in materials and medicinal chemistry. In this Letter, a wide variety of ortho-dihalogenated arylpyrimidines were synthesized with high yields and functional-group tolerance using calcium
