105976-34-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 105976-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,7 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 105976-34:
(8*1)+(7*0)+(6*5)+(5*9)+(4*7)+(3*6)+(2*3)+(1*4)=139
139 % 10 = 9
So 105976-34-9 is a valid CAS Registry Number.

Planar chiral dialkoxysilane: Introduction of inherent chirality and high reactivity in conventional achiral alkene

Tomooka, Katsuhiko,Miyasaka, Shouji,Motomura, Shougo,Igawa, Kazunobu

supporting information, p. 7598 - 7602 (2014/07/07)

A simple eight-membered dialkoxysilane (E)-1 prepared from 2-pentene-1,5-diol, showed remarkably stable planar chirality along with high reactivity toward epoxidation, Diels-Alder reaction, and cycloaddition reaction with azide. Enriching alkenes: A simple eight-membered dialkoxysilane, prepared from 2-pentene-1,5-diol, shows remarkably stable planar chirality along with quite a high reactivity in epoxidation reactions, Diels-Alder reactions, and in cycloaddition reactions with azide (see scheme).

Rhenium-catalyzed synthesis of naphthalene derivatives via insertion of aldehydes into a C-H bond

Kuninobu, Yoichiro,Nishina, Yuta,Takai, Kazuhiko

, p. 8463 - 8468 (2008/02/09)

A rhenium complex, [ReBr(CO)3(THF)]2, catalyzed reactions of aromatic ketimines and aldehydes with dienophiles, followed by dehydration, to give naphthalene derivatives in good to excellent yields. This reaction proceeds via C-H bond activation, insertion of an aldehyde, intramolecular nucleophilic cyclization, reductive elimination, elimination of aniline and Diels-Alder reaction. After dehydration, naphthalene derivatives were formed.
