75726-98-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75726-98-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,2 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75726-98:
(7*7)+(6*5)+(5*7)+(4*2)+(3*6)+(2*9)+(1*8)=166
166 % 10 = 6
So 75726-98-6 is a valid CAS Registry Number.

Asymmetric syntheses of three-membered heterocycles using chiral amide-based ammonium ylides

Pichler, Mathias,Novacek, Johanna,Robiette, Raphal,Poscher, Vanessa,Himmelsbach, Markus,Monkowius, Uwe,Müller, Norbert,Waser, Mario

supporting information, p. 2092 - 2099 (2015/03/05)

The use of carbonyl-stabilised ammonium ylides to access chiral glycidic amides and the corresponding aziridines has so far been limited to racemic trans-selective protocols. We herein report the development of an asymmetric approach to access such compou

ELECTROPHILIC ASYMMETRIC SYNTHESES OF α-HYDROXY CARBOXYLIC ACIDS

Ludwig, Jerry W.,Newcomb, Martin,Bergbreiter, David E.

, p. 2731 - 2734 (2007/10/02)

Asymmetric electrophilic syntheses of α-hydroxy carboxylic acids from chiral amide derivatives of tert-butyl- and trialkylsilyl- protected glycolic and lactic acids are described which lead to chiral α-hydroxy carboxylic acids in 60-95percent diastereomeric excess.
