Check Digit Verification of cas no

The CAS Registry Mumber 59574-65-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,5,7 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 59574-65:
(7*5)+(6*9)+(5*5)+(4*7)+(3*4)+(2*6)+(1*5)=171
171 % 10 = 1
So 59574-65-1 is a valid CAS Registry Number.

Palladium nanoparticlesin situsynthesized onCyclea barbatapectin as a heterogeneous catalyst for Heck coupling in water, the reduction of nitrophenols and alkynes

, p. 4746 - 4755 (2021/03/22)

This study develops an effective method for thein situsynthesis of palladium nanoparticles (PdNPs) usingCyclea barbatapectin as a green reducing and stabilizing reagent. The PdNP@pectin nanocomposite was well characterized by analysis techniques such as UV-vis, FTIR, EDX, XRD, SEM, HR-TEM and STEM-mapping. Crystalline PdNPs were found to be distributed in the size range of 1-25 nm with the highest frequency of 6-12 nm. PdNP@pectin exhibited excellent recyclable catalysis activity for the Heck coupling reaction in water medium. The kinetics and recyclability of nanoparticles were investigated for the catalytic reduction ofo-,m- andp-nitrophenol. The result showed a good catalysis efficiency with five successful recycles without compromising much. In particular, the nanocomposite was used as a catalyst for the conversion of alkynes intocis-alkenes with KOH/DMF as a hydrogenation source. The reaction was also utilized effectively for the synthesis of sex pheromones, includingPlutella xylostella((Z)-11-hexadecen-1-yl acetate) andCylas formicarius((Z)-3-dodecen-1-yl(E)-2-butenoate) with the total yields of 70% and 68%, respectively. Therefore, PdNPs supported onC. barbatapectin are promising catalysis materials for application in various fields.

Enantioselective Hydroformylation of 1-Alkenes with Commercial Ph-BPE Ligand

Yu, Zhiyong,Eno, Meredith S.,Annis, Alexandra H.,Morken, James P.

supporting information, p. 3264 - 3267 (2015/07/15)

A rhodium complex, in conjunction with commercially available Ph-BPE ligand, catalyzes the branch-selective asymmetric hydroformylation of 1-alkenes and rapidly generates α-chiral aldehydes. A wide range of terminal olefins including 1-dodecene were examined, and all delivered high enantioselectivity (up to 98:2 er) as well as good branch:linear ratios (up to 15:1).

Mechanistic studies of an isph-catalyzed reaction: Implications for substrate binding and protonation in the biosynthesis of isoprenoids

Chang, Wei-Chen,Xiao, Youli,Liu, Hung-Wen,Liu, Pinghua

scheme or table, p. 12304 - 12307 (2012/02/02)

Chosen handle: Mechanistic studies of the IspH-catalyzed reductive dehydroxylation of 4-hydroxy-3-methyl-2-(E)-1-diphosphate (HMBPP) to isopentenyl diphosphate and dimethylallyl diphosphate suggest that both the 4-OH group and the double bond of HMBPP may contribute to the formation of substrate-IspH complex. Labeling studies now show that the 4-hydroxy group of the substrate plays the dominant role in positioning the substrate in the enzyme active site.

O -substituted alkyl aldehydes for rhodium-catalyzed intermolecular alkyne hydroacylation: The utility of methylthiomethyl ethers

Parsons, Scott R.,Hooper, Joel F.,Willis, Michael C.

supporting information; experimental part, p. 998 - 1000 (2011/05/15)

Combining α-methylthiomethyl (MTM) ether substituted aldehydes and 1-alkynes in the presence of [Rh(dppe)]ClO4 results in efficient intermolecular alkyne hydroacylation to deliver α-O-MTM-substituted enone products. The product MTM ethers can be converted to the free hydroxyl group either in situ, by the addition of water to the completed reaction, or in a separate operation, by the action of silver nitrate.(Figure Presented)
