501330-43-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 501330-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,3,3 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 501330-43:
(8*5)+(7*0)+(6*1)+(5*3)+(4*3)+(3*0)+(2*4)+(1*3)=84
84 % 10 = 4
So 501330-43-4 is a valid CAS Registry Number.

Enantioselective synthesis of butadien-2-ylcarbinols via (silylmethyl)allenic alcohols from chromium-catalyzed additions to aldehydes utilizing chiral carbazole ligands

Durán-Galván, María,Worlikar, Shilpa A.,Connell, Brian T.

scheme or table, p. 7707 - 7719 (2010/10/21)

The synthesis of chiral, nonracemic butadienylcarbinols by employing intermediate (trimethylsilyl)methylallenic alcohols is described. Allenic alcohols are obtained by treatment of aldehydes with (4-bromobut-2-ynyl) trimethylsilane in the presence of a ca

Asymmetric catalysis of Nozaki-Hiyama allylation and methallylation with a new tridentate bis(oxazolinyl)carbazole ligand

Inoue, Masahiro,Suzuki, Takahiro,Nakada, Masahisa

, p. 1140 - 1141 (2007/10/03)

This work describes the development of a new tridentate ligand effective for the asymmetric catalysis of Nozaki-Hiyama allylation and methallylation. Various aldehydes were allylated or methallylated with good enantioselectivity (86-96%), and a key interm
