619-91-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 619-91-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 619-91:
(5*6)+(4*1)+(3*9)+(2*9)+(1*1)=80
80 % 10 = 0
So 619-91-0 is a valid CAS Registry Number.

Mechanosynthesis of sydnone-containing coordination complexes

Pétry, Nicolas,Vanderbeeken, Thibaut,Malher, Astrid,Bringer, Yoan,Retailleau, Pascal,Bantreil, Xavier,Lamaty, Frédéric

supporting information, p. 9495 - 9498 (2019/08/15)

N-Phenyl-4-(2-pyridinyl) sydnone was shown to act as a four-electron donor N,O-ligand in unprecedented coordination complexes featuring three different metallic centers (Co, Cu, and Zn). Starting with various anilines, the use of a ball-mill efficiently enabled the synthesis of N-arylglycines, subsequent nitrosylation and cyclization into sydnones, and further metalation.

Cu(II)-catalyzed C-N coupling of (hetero)aryl halides and N-Nucleophiles promoted by α-benzoin oxime

Yuan, Chunling,Zhang, Lei,Zhao, Yingdai

, (2019/11/28)

We first reported the new application of a translate metal chelating ligand α-benzoin oxime for improving Cu-catalyzed C-N coupling reactions. The system could catalyse coupling reactions of (hetero)aryl halides with a wide of nucleophiles (e.g., azoles, piperidine, pyrrolidine and amino acids) in moderate to excellent yields. The protocol allows rapid access to the most common scaαolds found in FDA-approved pharmaceuticals.

Photo-polymerization properties of type-II photoinitiator systems based on 2-chlorohexaaryl biimidazole (o-Cl-HABI) and various N-phenylglycine (NPG) derivatives

Chen, Yung-Chung,Kuo, Yuan-Tsung,Ho, Tsung-Han

, p. 190 - 197 (2019/01/21)

A series of p-substituted NPG derivatives (Cl-NPG, OMe-NPG and NO2-NPG) comprising different push-pull characteristics have been synthesized and characterized. The NPG derivatives have good thermal stability and red shifted absorption when comp
