1221072-20-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1221072-20-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,0,7 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1221072-20:
(9*1)+(8*2)+(7*2)+(6*1)+(5*0)+(4*7)+(3*2)+(2*2)+(1*0)=83
83 % 10 = 3
So 1221072-20-3 is a valid CAS Registry Number.

Coumarin-based emissive hexacatenars: synthesis, 2D and 3D self-assembly and photodimerization

Xiao, Yulong,Tan, Xiaoping,Xing, Wei,Zhao, Kai,Zhang, Bei,Cheng, Xiaohong

, p. 10782 - 10792 (2018)

The first examples of unsymmetric coumarin polycatenar liquid crystals consisting of a coumarin central core with 1,2,3-triazole dendritic wings on both sides were synthesized via click reaction. Their properties were investigated using POM, DSC, XRD, SEM

Triblock polyphiles through click chemistry: Self-assembled thermotropic cubic phases formed by micellar and monolayer vesicular aggregates

Tan, Xiaoping,Kong, Leiyang,Dai, Heng,Cheng, Xiaohong,Liu, Feng,Tschierske, Carsten

supporting information, p. 16303 - 16313 (2013/12/04)

Three series of triblock polyphiles consisting of a rigid 4-phenyl-1,2,3-triazole or 1,4-diphenyl-1,2,3-triazole core with three lipophilic and flexible alkoxyl chains at one end and a polar glycerol group at the opposite end were synthesized by copper-ca

Design, synthesis, and self-assembly behavior of C3-symmetry discotic molecules via click chemistry

Ryu, Mi-Hee,Choi, Jin-Woo,Cho, Byoung-Ki

experimental part, p. 1806 - 1810 (2010/07/08)

We prepared a series of C3-symmetry discogens with three 1,2,3-triazoles and a central benzene ring by a copper-catalyzed "click reaction" between 1,3,5-triethynylbenzene and 3,4,5-trialkoxybenzyl azides. According to the differential scanning
