19405-98-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19405-98-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,0 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19405-98:
(7*1)+(6*9)+(5*4)+(4*0)+(3*5)+(2*9)+(1*8)=122
122 % 10 = 2
So 19405-98-2 is a valid CAS Registry Number.

A microchemical system with continuous recovery and recirculation of catalyst-immobilized magnetic particles

Park, Chan Pil,Kim, Dong-Pyo

, p. 6825 - 6829 (2010)

(Figure Presented) Keep on running: A microchemical system for continuous flow catalytic reactions with a magnetic catalyst is presented (see picture). It enables the automatic separation and recirculation of catalyst particles and is applicable to various catalytic reactions.

Oxidative transformation of cyclic ethers/amines to lactones/lactams using a DIB/TBHP protocol

Zhao, Yi,Ang, Jascelyn Qian Lin,Ng, Angela Wan Ting,Yeung, Ying-Yeung

, p. 19765 - 19768 (2013/11/06)

A novel C-H oxidation of cyclic ethers and amines to the corresponding lactones and lactams was developed using a DIB/TBHP protocol. The reaction is mild and no metallic reagent is involved. In addition, study shows that the electronic properties of the substituents could affect the selectivity of oxidation. The Royal Society of Chemistry 2013.

Baeyer-villiger oxidation and oxidative cascade reactions with aqueous hydrogen peroxide catalyzed by lipophilic Li[B(C6F5) 4] and Ca[B(C6F5)4]2

Uyanik, Muhammet,Nakashima, Daisuke,Ishihara, Kazuaki

supporting information, p. 9093 - 9096 (2012/11/07)

Efficient and selective: Two lipophilic catalysts were used for Baeyer-Villiger (BV) oxidations to give lactones in high yields (see scheme). Cascade reactions involving this BV oxidation were used to selectively obtain either unsaturated carboxylic acids or hydroxylactones in high yields from β-silyl cyclohexanones. Copyright
