25559-56-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25559-56-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,5 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25559-56:
(7*2)+(6*5)+(5*5)+(4*5)+(3*9)+(2*5)+(1*6)=132
132 % 10 = 2
So 25559-56-2 is a valid CAS Registry Number.

Unique features of chiral palladium enolates derived from β-ketoamide: structure and catalytic asymmetric Michael and fluorination reactions

Hayamizu, Kenji,Terayama, Naoki,Hashizume, Daisuke,Dodo, Kosuke,Sodeoka, Mikiko

, p. 6594 - 6601 (2015)

Abstract We have previously reported enantioselective reactions of 1,3-diketones and β-ketoesters with various electrophiles catalyzed by chiral Pd complex, in which chiral Pd enolates play a key role. Here, we present a detailed examination of Pd-catalyz

Enantioselective α-hydroxylation of -ketoamides

De Fusco, Claudia,Meninno, Sara,Tedesco, Consiglia,Lattanzi, Alessandra

supporting information, p. 896 - 899 (2013/02/26)

The first enantioselective α-hydroxylation reaction of α-substituted -ketoamides has been developed by using the commercially available hydroquinine/TBHP system. The tertiary alcohols are obtained in good to high yield and up to 83% ee, which can be improved by a single crystallization.
