Check Digit Verification of cas no

The CAS Registry Mumber 601454-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,1,4,5 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 601454-31:
(8*6)+(7*0)+(6*1)+(5*4)+(4*5)+(3*4)+(2*3)+(1*1)=113
113 % 10 = 3
So 601454-31-3 is a valid CAS Registry Number.

Phosphorus(V) porphyrins with axial carbazole-based dendritic substituents

Xu, Tinghua,Lu, Ran,Liu, Xingliang,Zheng, Xiangqian,Qiu, Xianping,Zhao, Yingying

, p. 797 - 800 (2007)

(Chemical Equation Presented) Three phosphorus(V) porphyrins with axial carbazole-based dendritic substituents (D-A-D) have been designed and synthesized, which are nonfluorescent due to their effective electron transfer from the carbazole dendron to the

Copper/β-diketone-catalysed N-arylation of carbazoles

Chen, Fei,Liu, Ning,Ji, Enhui,Dai, Bin

, p. 51512 - 51523 (2015/06/25)

A copper-catalysed C-N bond-forming reaction of carbazoles with aryl iodides is described. Several commercially available ligands such as β-diketone and diamine, are tested in the N-arylation of carbazoles. The catalytic system generated in situ from an inexpensive copper salt, simple β-diketone and inorganic base efficiently N-arylated the carbazoles. A wide range of aryl iodides and carbazoles can be coupled to generate N-arylcarbazoles in the presence of various functional groups. However, the sterically hindered effect of aryl iodides is evident in this catalytic system. The selectivity of two iodine atoms on the aromatic ring of diiodobenzene is evaluated in the developed catalytic system. Results showed that the selectivity of diiodobenzene can be tuned by the reaction temperature.
