1434057-17-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1434057-17-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,4,0,5 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1434057-17:
(9*1)+(8*4)+(7*3)+(6*4)+(5*0)+(4*5)+(3*7)+(2*1)+(1*7)=136
136 % 10 = 6
So 1434057-17-6 is a valid CAS Registry Number.

Heterogeneous sequential N-arylation of N-heterocycles over copper anchored mesoporous silica catalyst

Das, Soma,Maity, Tanmoy,Koner, Subratanath

, p. 53 - 66 (2016/01/12)

N-Arylation reaction of N-heterocyclic compounds has been carried out in excellent yield using copper anchored SBA-15 catalyst. Sequential N-arylation reactions employing single catalyst under heterogeneous condition provides a straightforward access to a

Copper-catalyzed direct aryl quaternization of N-substituted imidazoles to form imidazolium salts

Lv, Taiyong,Wang, Zhi,You, Jingsong,Lan, Jingbo,Gao, Ge

, p. 5723 - 5730 (2013/07/26)

Diaryliodonium salts are employed to directly quaternize N-substituted imidazoles by using a copper catalyst to construct aryl imidazolium salts in moderate to excellent yields. This transformation is tolerant to a broad range of functional groups and provides a straightforward, efficient, and versatile route to synthesize aryl imidazolium as well as triazolium salts, especially the unsymmetric version.
