1133970-57-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1133970-57-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,9,7 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1133970-57:
(9*1)+(8*1)+(7*3)+(6*3)+(5*9)+(4*7)+(3*0)+(2*5)+(1*7)=146
146 % 10 = 6
So 1133970-57-6 is a valid CAS Registry Number.

Diastereoselective synthesis of propargylamines catalyzed by Cu-MCM-41

Cortezano-Arellano, Omar,Hernández-Gasca, Miguel A.,ángeles-Beltrán, Deyanira,Negrón-Silva, Guillermo E.,Santillan, Rosa

supporting information, p. 2403 - 2406 (2018/05/25)

In this work, a rapid, efficient and protecting group free diastereoselective synthesis of propargylamines through a multicomponent coupling reaction between (S)-prolinol, phenylacetylene and commercially available aldehydes catalyzed by Cu-MCM-41 in hete

Gold(III) (C^N) complex-catalyzed synthesis of propargylamines via a three-component coupling reaction of aldehydes, amines and alkynes

Lo, Vanessa Kar-Yan,Kung, Karen Ka-Yan,Wong, Man-Kin,Che, Chi-Ming

experimental part, p. 583 - 591 (2009/06/05)

Propargylamines are synthesized in high yields via a gold(III) (C^N) complex-catalyzed three-component coupling reaction of aldehydes, amines and alkynes in water at 40 °C. Excellent diastereoselectivities (up to 99:1) have been achieved when chiral prolinol derivatives are employed as the amine component. Notably, the [Au(C^N)Cl2] complex (N^CH = 2-phenylpyridine) could be repeatedly used for 10 reaction cycles, leading to an overall turnover number of 812.
