21164-57-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21164-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,6 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21164-57:
(7*2)+(6*1)+(5*1)+(4*6)+(3*4)+(2*5)+(1*7)=78
78 % 10 = 8
So 21164-57-8 is a valid CAS Registry Number.

STUDIES ON ENAMIDES. PART-3 : A NOVEL PHOTOCHEMICAL SYNTHESIS OF 9-ARYLACRIDINES

Datta, Indira,Das, Tapas Kumar,Ghosh, Somnath

, p. 4009 - 4012 (1989)

A unique synthesis of 9-arylacridines has been achieved by the photolysis of N-aroyldiphenylamines alongwith carbazole and photomigrated products.

A magnetic nanoparticle-supported N-heterocyclic carbene-palladacycle: An efficient and recyclable solid molecular catalyst for Suzuki-Miyaura cross-coupling of 9-chloroacridine

Deng, Qinyue,Shen, Yajing,Zhu, Haibo,Tu, Tao

supporting information, p. 13063 - 13066 (2017/12/15)

A robust magnetic nanoparticle-supported N-heterocyclic carbene-palladacycle has been readily synthesized by directly anchoring the structural defined acenaphthoimidazolylidene palladacycle with a long tail on magnetic nanoparticles (MNPs), and functioned as a solid molecular catalyst and exhibited extremely high catalytic activity towards the challenging Suzuki-Miyaura cross-coupling reactions between less-studied heterocyclic 9-chloroacridine and diverse boronic acids. Remarkably, the catalyst could be used 5 times without obvious loss of activity highlighting the efficiency of our strategy of immobilization of previledged catalysts.
