56964-65-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 56964-65-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,9,6 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 56964-65:
(7*5)+(6*6)+(5*9)+(4*6)+(3*4)+(2*6)+(1*5)=169
169 % 10 = 9
So 56964-65-9 is a valid CAS Registry Number.

Asymmetric Intramolecular Hydroalkoxylation of Unactivated Alkenes Catalyzed by Chiral N-Triflyl Phosphoramide and TiCl4?

Cheng, Aolin,Li, Yingkun,Ma, Jiguo,Wang, Xinxu,Zhang, Yi,Zhao, Baoguo,Zhao, Guoqing,Zhao, Pengyuan

supporting information, p. 565 - 569 (2020/04/23)

By using a combination of a chiral N-triflyl phosphoramide and TiCl4 as the catalyst, a new process for asymmetric intramolecular hydroalkoxylation of unactivated alkenes was developed, producing various chiral tetrahydrofuran derivatives in 51%—99% yields with 30%—71% ee's.

Combined dealkoxycarbonylation and lactonisation of unsaturated malonates in ionic liquids

Oswald, Magalie F.,Parsons, Andrew F.,Yang, Wei,Bowden, Martin

, p. 8087 - 8089 (2007/10/03)

Heating unsaturated malonates with LiCl and water in [bmim][Br] or [bmim][BF4]/[bmim][Br] produces unsaturated esters or lactones, respectively.

Acylations and Alkylations of an Ester Enolate in High Yield at Room Temperature on Polystyrene Supports

Chang, Young H.,Ford, Warren T.

, p. 3756 - 3758 (2007/10/02)

Polymer-bound esters of 3-phenylpropanoic acid are converted to enolates at room temperature and acylated and alkylated in 73-87percent isolated yields with little or no self-condensation of ester.
