130059-81-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130059-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,0,5 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130059-81:
(8*1)+(7*3)+(6*0)+(5*0)+(4*5)+(3*9)+(2*8)+(1*1)=93
93 % 10 = 3
So 130059-81-3 is a valid CAS Registry Number.

Highly enantioselective epoxidation of 2,4-diarylenones by using dimeric cinchona phase-transfer catalysts: Enhancement of enantioselectivity by surfactants

Jew, Sang-Sup,Lee, Jeong-Hee,Jeong, Byeong-Seon,Yoo, Mi-Sook,Kim, Mi-Jeong,Lee, Yeon-Ju,Lee, Jihye,Choi, Sea-Hoon,Lee, Kyungjae,Lah, Myoung Soo,Park, Hyeung-Geun

, p. 1383 - 1385 (2005)

Dramatic increases in reaction rates and enantioselectivities can be effected by the use of surfactants for the phase-transfer catalytic epoxidation of aromatic enones. Based on the X-ray crystal structure of the most effective catalyst-a modified cinchona alkaloid-a plausible transition state of the reaction has been modeled (see picture; HOO- yellow, C gray, H white, N blue, O red).

Heterogenization of Shibasaki's binol/La catalyst for enantioselective epoxidation of α,β-unsaturated ketones with multitopic binol ligands: The impact of bridging spacers

Wang, Xingwang,Shi, Lei,Li, Mingxing,Ding, Kuiling

, p. 6362 - 6366 (2005)

(Figure Presented) Bridging the gap: Heterogenized Shibasaki's binol/La catalyst is synthesized by a self-supporting strategy through the reactions of multitopic ligands with La(OiPr)3 (see picture). The catalyst shows high activity and enantioselectivity, and can be reused in the asymmetric epoxidation of α,β-unsaturated ketones.

Asymmetric epoxidation of α,β-unsaturated ketones catalyzed by rare-earth metal amides RE[N(SiMe3)2]3with chiral TADDOL ligands

Shan, Haiwen,Lu, Chengrong,Zhao, Bei,Yao, Yingming

, p. 1043 - 1053 (2021/01/25)

The catalytic asymmetric epoxidation of α,β-unsaturated ketones by tert-butylhydroperoxide (TBHP) has been well established using rare-earth metal amides RE[N(SiMe3)2]3 (RE = La(1), Nd(2), Sm(3), Y(4), Yb(5)) with chiral TADDOL ligands. It was found that

Ligand regulation for manganese-catalyzed enantioselective epoxidation of olefins without acid

Xu, Daqian,Sun, Qiangsheng,Lin, Jin,Sun, Wei

supporting information, p. 13101 - 13104 (2020/11/09)

A novel manganese catalyst bearing an l-proline-derived N4 ligand has been developed for enabling acid-free asymmetric epoxidation of olefins with tert-butyl hydroperoxide as the oxidant. A variety of olefins that are well-matched in size with the ligand
