161170-64-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 161170-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,7 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161170-64:
(8*1)+(7*6)+(6*1)+(5*1)+(4*7)+(3*0)+(2*6)+(1*4)=105
105 % 10 = 5
So 161170-64-5 is a valid CAS Registry Number.

Asymmetric synthesis of methyl N-(1-phenylethyl)-3-aza-10-oxatricyclo[5.2.1.01,5]-4-oxo dec-8-en-6-carboxylate by an intramolecular Diels-Alder reaction

Zylber,Tubul,Brun

, p. 377 - 380 (1995)

The title compound can be obtained with up to five asymmetric centres of known absolute configuration by a diastereoselective intramolecular Diels-Alder reaction between optically active N-substituted furfurylamines and maleic anhydride, in which the chir

One-pot solvent-free reductive amination with a solid ammonium carbamate salt from CO2 and amine

Kang, Philjun,Lee, Kyu Myung,Lee, Won Koo,Lee, Kyu Hyung,Lee, Byeongno,Cho, Jaeheung,Hur, Nam Hwi

, p. 46203 - 46207 (2015/02/19)

Many amines are liquid and their handling is inconvenient compared with the corresponding solids. We transformed a liquid (S)-(-)-1-phenylethylamine 1 to the corresponding neutral solid form 2 by reacting with carbon dioxide. We performed reductive aminat

Scope of the organocatalysed asymmetric reductive amination of ketones with trichlorosilane

Gautier, Franois-Moana,Jones, Simon,Li, Xianfu,Martin, Stephen J.

experimental part, p. 7860 - 7868 (2011/12/02)

A highly active organocatalyst has been shown to affect the asymmetric reductive amination of ketones producing both aromatic and aliphatic amines. At 1 mol% catalyst loading, a series of structurally diverse chiral amines were quickly and economically prepared with good enantioselectivity and generally useful yield. The efficient synthesis of the calcimimetic (+)-NPS R-568 (67%, 89% ee) demonstrated the synthetic applicability of this methodology.
