505087-61-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 505087-61-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,5,0,8 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 505087-61:
(8*5)+(7*0)+(6*5)+(5*0)+(4*8)+(3*7)+(2*6)+(1*1)=136
136 % 10 = 6
So 505087-61-6 is a valid CAS Registry Number.

Gold-catalyzed oxidative reactions of propargylic carbonates involving 1,2-carbonate migration: Stereoselective synthesis of functionalized alkenes

Sun, Ning,Chen, Ming,Liu, Yuanhong

, p. 4055 - 4067 (2014/05/20)

A gold-catalyzed oxidative reaction of propargylic carbonates or acetates using 3,5-dichloropyridine as the oxidant has been developed. The reaction provides efficient access to α-functionalized-α,β-unsaturated ketones with excellent regio- and diastereoc

Asymmetric palladium-catalyzed annulation of benzene-1,2-diol and racemic secondary propargylic carbonates bearing two different substituents

Dominczak, Norbert,Damez, Céline,Rhers, Bouchra,Labrosse, Jean-Robert,Lhoste, Paul,Kryczka, Boguslaw,Sinou, Denis

, p. 2589 - 2599 (2007/10/03)

The palladium-catalyzed cyclization of benzene-1,2-diol with various racemic secondary propargyl carbonates having no acetylenic hydrogen in the presence of (R)-Binap as the chiral ligand afforded the two regioisomers of the corresponding 2,3-dihydro-1,4-
