357952-86-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 357952-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,9,5 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 357952-86:
(8*3)+(7*5)+(6*7)+(5*9)+(4*5)+(3*2)+(2*8)+(1*6)=194
194 % 10 = 4
So 357952-86-4 is a valid CAS Registry Number.

Diastereoselective Alkene Hydroesterification Enabling the Synthesis of Chiral Fused Bicyclic Lactones

Shi, Zhanglin,Shen, Chaoren,Dong, Kaiwu

, p. 18039 - 18042 (2021/11/16)

Palladium-catalysed diastereoselective hydroesterification of alkenes assisted by the coordinative hydroxyl group in the substrate afforded a variety of chiral γ-butyrolactones bearing two stereocenters. Employing the carbonylation-lactonization products as the key intermediates, the route from the alkenes with single chiral center to chiral THF-fused bicyclic γ-lactones containing three stereocenters was developed.

Convenient synthesis of optically active 1,2-diol monosulfonates and terminal epoxides via oxazaborolidine-catalyzed asymmetric borane reduction of α-sulfonyloxy ketones

Cho, Byung Tae,Yang, Weon Ki,Choi, Ok Kyung

, p. 1204 - 1211 (2007/10/03)

A very convenient asymmetric synthesis of 1,2-diol monosulfonates and terminal epoxides with high optical purity via oxazaborolidine-catalyzed asymmetric borane reduction of α-sulfonyloxy ketones using N-ethyl-N-isopropylaniline-borane complex as borane carrier has been developed.
