Check Digit Verification of cas no

The CAS Registry Mumber 90891-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,9 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90891-21:
(7*9)+(6*0)+(5*8)+(4*9)+(3*1)+(2*2)+(1*1)=147
147 % 10 = 7
So 90891-21-7 is a valid CAS Registry Number.

Catalytic Staudinger Reduction at Room Temperature

Lenstra, Danny C.,Wolf, Joris J.,Mecinovi?, Jasmin

, p. 6536 - 6545 (2019/05/24)

We report an efficient catalytic Staudinger reduction at room temperature that enables the preparation of a structurally diverse set of amines from azides in excellent yields. The reaction is based on the use of catalytic amounts of triphenylphosphine as a phosphine source and diphenyldisiloxane as a reducing agent. Our catalytic Staudinger reduction exhibits a high chemoselectivity, as exemplified by reduction of azides over other common functionalities, including nitriles, alkenes, alkynes, esters, and ketones.

Asymmetric transfer hydrogenation of β,γ-alkynyl α-lmino esters by a bronsted acid

Kang, Qiang,Zhao, Zhuo-An,You, Shu-Li

scheme or table, p. 2031 - 2034 (2009/04/10)

Asymmetric synthesis of trans-alkenyl α-amino esters was realized by chiral phosphoric acid catalyzed transfer hydrogenatlon of β,γ- alkynyl α-imino esters. Utilizing Hantzsch esters as the hydrogen donor, both the alkyne and Imine moieties of β,γ-alkynyl

Ethyl 2,4-dioxo-4-phenylbutyrate: A versatile intermediate for the large-scale preparation of enantiomerically pure α-hydroxy and α-amino acid esters

Blaser, Hans-Ulrich,Burkhardt, Stephan,Kirner, Hans Juerg,Moessner, Tanja,Studer, Martin

, p. 1679 - 1682 (2007/10/03)

Starting from ethyl 2,4-dioxo-4-phenylbutyrate, both enantiomers of six enantiomerically pure α-hydroxy and α-amino acid esters (homophenylalanine derivatives) were prepared on >100 g scale. The key step involves a Pt-cinchona catalyzed enantioselective hydrogenation followed by enrichment via crystallization. All derivatives are commercially available.
