Check Digit Verification of cas no

The CAS Registry Mumber 1189116-34-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,1,1 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1189116-34:
(9*1)+(8*1)+(7*8)+(6*9)+(5*1)+(4*1)+(3*6)+(2*3)+(1*4)=164
164 % 10 = 4
So 1189116-34-4 is a valid CAS Registry Number.

Fluorous bispidine: A bifunctional reagent for copper-catalyzed oxidation and knoevenagel condensation reactions in water

Ang, Wei Jie,Chng, Yong Sheng,Lam, Yulin

, p. 81415 - 81428 (2015/10/06)

Fluorous bispidine-type ligands have been developed to facilitate its recovery and reusability and to demonstrate its bifunctional property as a ligand and base in copper-catalyzed aerobic oxidation, the Knoevenagel condensation and tandem oxidation/Knoevenagel condensation in water under mild conditions. Application of the fluorous ligand was also extended to the surfactant-free copper-catalyzed allylic and benzylic sp3 C-H oxidation reaction in water. The fluorous ligands could be recovered using F-SPE with recovery ranging from 91-97% and could be reused five times with little loss of activity.

Diels-Alder reactions of acyclic α-cyano α,β-alkenones: a new approach to highly substituted cyclohexene system

Amancha, Prashanth K.,Lai, Yi-Chun,Chen, I.-Chia,Liu, Hsing-Jang,Zhu, Jia-Liang

experimental part, p. 871 - 877 (2010/03/25)

The Diels-Alder reactions of a variety of acyclic α-cyano α,β-unsaturated ketones 8 have been investigated. With the assistance of boron trichloride, these compounds were found to undergo the cycloaddition readily with dienes to give the corresponding add
