109808-84-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109808-84-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,0 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109808-84:
(8*1)+(7*0)+(6*9)+(5*8)+(4*0)+(3*8)+(2*8)+(1*4)=146
146 % 10 = 6
So 109808-84-6 is a valid CAS Registry Number.

Enantioselective Oxidative Aerobic Dealkylation of N-Ethyl Benzylisoquinolines by Employing the Berberine Bridge Enzyme

Gandomkar, Somayyeh,Fischereder, Eva-Maria,Schrittwieser, Joerg H.,Wallner, Silvia,Habibi, Zohreh,Macheroux, Peter,Kroutil, Wolfgang

, p. 15051 - 15054 (2016/01/25)

N-Dealkylation methods are well described for organic chemistry and the reaction is known in nature and drug metabolism; however, to our knowledge, enantioselective N-dealkylation has not been yet reported. In this study, exclusively the (S)-enantiomers o

Synthesis of 8-oxoberbines and related benzolactams by Pd(OAc) 2-catalyzed direct aromatic carbonylation

Miyazawa, Mamoru,Tokuhashi, Takashi,Horibata, Akiyoshi,Nakamura, Takatoshi,Onozaki, Yu,Kurono, Nobuhito,Senboku, Hisanori,Tokuda, Masao,Ohkuma, Takeshi,Orito, Kazuhiko

, p. E48-E54 (2013/06/05)

A variety of alkoxy-substituted benzolactams with a berbine or yohimbane skeleton were prepared from 1-benzyl-1,2,3,4-tetrahydroisoquinolines or 1-benzyl-1,2,3,4-tetrahydro-β-carbolines by a phosphine-free Pd(II)-catalyzed direct aromatic carbonylation in a Pd(OAc)2-Cu(OAc) 2 catalytic system. The site selectivity was compared with that of the carbonylation with Pd(OAc)2 or Pd(OAc)2·2 PPh3, respectively.
