130857-97-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130857-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,5 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130857-97:
(8*1)+(7*3)+(6*0)+(5*8)+(4*5)+(3*7)+(2*9)+(1*7)=135
135 % 10 = 5
So 130857-97-5 is a valid CAS Registry Number.

N,N'-dialkylated 1,2-diamine derivatives as new efficient ligands for RuCl2(PPh3)3 catalyzed asymmetric transfer hydrogenation of aromatic ketones

Kim, Geon-Joong,Kim, Sang-Han,Chong, Pong-Hyun,Kwon, Mi-Ae

, p. 8059 - 8062 (2007/10/03)

Chiral N,N'-dialkylated cyclohexanediamine derivatives ligands have been synthesized and used in an asymmetric transfer hydrogenation of aryl ketones. Optically active alcohols with up to 93% enantiomeric excess were obtained in high yield.

SPECTRES RMN-1H ET -13C DE PHENYL-1-PROPANEDIAMINES-1,2 DERIVES DE L'EPHEDRINE ET DE LEURS IMIDAZOLIDINES

Tytgat, D.,Gelbcke, M.

, p. 243 - 256 (2007/10/02)

A series of N1-methyl-1-phenyl-1,2-propanediamines substituted at the nitrogen (N2) by alkyl groups (CH3, C2H5, i-C3H7, t-C4H9) and the corresponding imidazolidines from formaldehyde have been synthesized.The study of their 1H- and 13C-NMR spectra allowed the differentiation of the diastereoisomers in these two series.
