Check Digit Verification of cas no

The CAS Registry Mumber 293768-77-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,3,7,6 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 293768-77:
(8*2)+(7*9)+(6*3)+(5*7)+(4*6)+(3*8)+(2*7)+(1*7)=201
201 % 10 = 1
So 293768-77-1 is a valid CAS Registry Number.

Novel N,S- and N,Se-planar chiral [2,2]paracyclophane ligands: Synthesis and application in Pd-catalyzed allylic alkylation

Hou, Xue-Long,Wu, Xun-Wei,Dai, Li-Xin,Cao, Bo-Xun,Sun, Jie

, p. 1195 - 1196 (2000)

Novel N,S- and N,Se-ligands with planar chirality derived from [2.2]paracyclophane have been synthesized and applied in palladium-catalyzed allylic alkylation reaction, in which ligands 5 and 9 with the two substituents at benzylic and benzene ring positi

[2.2]Paracyclophanes with N-Heterocycles as Ligands for Mono- and Dinuclear Ruthenium(II) Complexes

Braun, Carolin,Nieger, Martin,Thiel, Werner R.,Br?se, Stefan

, p. 15474 - 15483 (2017/11/09)

[2.2]Paracyclophane, with its unique structure, allows the design of unusual 3D structures by functionalization of this rigid and stable hydrocarbon scaffold. Therefore different mono- and homodisubstituted [2.2]paracyclophanes with pyridyl, pyrimidyl and oxazolinyl substituents were developed in order to evaluate their ability as bridging ligands for two ruthenium centres. With the successfully synthesized [2.2]paracyclophane-based N-donor functions, the cycloruthenation reaction using [RuCl2(p-cymene)]2 as precursor was explored. Compared to 2-phenylpyridine, the [2.2]paracyclophane derivative is clearly inferior in the cycloruthenation reaction, resulting in poor yields for the neutral complexes. By addition of KPF6, the cationic complexes can be obtained in good yields and are formed diastereoselectively in case of a pyridyl substituent, resulting in only one diastereomer for dinuclear ruthenium complexes of bispyridyl-substituted [2.2]paracyclophanes as bridging ligands.
