Check Digit Verification of cas no

The CAS Registry Mumber 64519-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,1 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 64519-09:
(7*6)+(6*4)+(5*5)+(4*1)+(3*9)+(2*0)+(1*9)=131
131 % 10 = 1
So 64519-09-1 is a valid CAS Registry Number.

In situ Generation of Hypervalent Iodine Reagents for the Electrophilic Chlorination of Arenes

Granados, Albert,Jia, Zhiyu,del Olmo, Marc,Vallribera, Adelina

, p. 2812 - 2818 (2019/04/08)

Efficient metal-free methods for the electrophilic chlorination of arenes using PIFA and simple chlorine sources are reported. The in situ formation of PhI(Cl)OCOCF3 from PIFA and KCl is proposed, which resulted in a chlorinating species for moderately activated arenes. Moreover, the in situ formation of PhICl2 from PIFA and TMSCl resulted in an excellent approach for the chlorination of a great variety of arenes (20 examples) in high yields, even when working on a multigram scale.

Aggregation-induced emission enhancement in halochalcones

Vaz, Patricia A. A. M.,Rocha, Jo?o,Silva, Artur M.S.,Guieu, Samuel

supporting information, p. 8198 - 8201 (2016/10/11)

A family of push-pull fluorophores, consisting of a chalcone core decorated with electron-donating substituents and halogen atoms, was designed and synthesized. Luminescence studies were performed in solution, aggregate form and in the solid state. Although some compounds are only weakly fluorescent in solution, all are emissive in the solid state showing aggregation-induced emission enhancement. In the crystalline state, the halogen atoms are not involved in halogen bonds but their presence strongly influences the aggregation-induced emission properties of the fluorophores.

Supramolecular organization of bis(3-halo-4-dimethylaminobenzylidene) hydrazines

Guieu, Samuel,Rocha, Jo?o,Silva, Artur M.S.

, p. 1 - 5 (2013/03/28)

Bis(3-bromo-4-dimethylaminobenzylidene)hydrazine and bis(3-chloro-4- dimethylaminobenzylidene)hydrazine have been synthesized, and their monoclinic crystal structures solved in space group P21/c. For the bromo derivative at 150 K, a = 10.4505(2

A facile, regioselective and controllable bromination of aromatic amines using a CuBr2/Oxone system

Li, Xin-Le,Wu, Wei,Fan, Xin-Heng,Yang, Lian-Ming

, p. 12091 - 12095 (2013/09/02)

A combination of cupric bromide and Oxone serves as a facile, mild and effective reagent for the bromination of aromatic amines. Primary, secondary and tertiary aromatic amines are all suitable substrates. The reaction possesses high regioselectivity and functional group tolerance, and mono- and multi-brominated products can be obtained controllably in moderate to excellent yields.
