3128-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3128-42-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,2 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3128-42:
(6*3)+(5*1)+(4*2)+(3*8)+(2*4)+(1*2)=65
65 % 10 = 5
So 3128-42-5 is a valid CAS Registry Number.

Zeolite Beta nanoparticles assembled Cu catalysts with superior catalytic performances in the synthesis of thioesters by cross-coupling of aldehydes and disulfides

Zheng, Xiang,Fu, Wenqian,Xiong, Jing,Xi, Jiachen,Ni, Xiaojun,Tang, Tiandi

, p. 152 - 157 (2016)

Development of the highly active and stable heterogeneous transition metal catalysts is of great importance in synthetic chemistry. Herein, zeolite Beta nanoparticles assembled Cu catalyst (Cu-Beta-Nano) with high external surface area was directly synthe

Rh(I)-Catalyzed Intramolecular Decarbonylation of Thioesters

Cao, Han,Liu, Xuejing,Bie, Fusheng,Shi, Yijun,Han, Ying,Yan, Peng,Szostak, Michal,Liu, Chengwei

, p. 10829 - 10837 (2021/07/28)

Decarbonylative synthesis of thioethers from thioesters proceeds in the presence of a catalytic amount of [Rh(cod)Cl]2 (2 mol %). The protocol represents the first Rh-catalyzed decarbonylative thioetherification of thioesters to yield valuable thioethers. Notable features include the absence of phosphine ligands, inorganic bases, and other additives and excellent group tolerance to aryl chlorides and bromides that are problematic using other metals to promote decarbonylation. Gram scale synthesis, late-stage pharmaceutical derivatization, and orthogonal site-selective cross-couplings by C-S/C-Br cleavage are reported.

Synthesis of selenol esters via the reaction of acyl chlorides with diselenides in the presence of Zn dust catalyzed by CoCl2·6H2O

Dall'Oglio, Evandro L.,Stein, André L.,Vasconcelos, Leonardo G.,Vieira, Lucas C. C.,de Oliveira, Angélica J.,de Oliveira, Sandynara A.

supporting information, (2021/08/25)

A practical and efficient approach for the synthesis of selenol and thiol esters is described via the reaction of acyl chlorides with diselenides or disulfides in the presence of Zn dust catalyzed by inexpensive CoCl2·6H2O This proto
