Check Digit Verification of cas no

The CAS Registry Mumber 160879-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,8,7 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 160879-62:
(8*1)+(7*6)+(6*0)+(5*8)+(4*7)+(3*9)+(2*6)+(1*2)=159
159 % 10 = 9
So 160879-62-9 is a valid CAS Registry Number.

Pd/BIPHEPHOS is an Efficient Catalyst for the Pd-Catalyzed S-Allylation of Thiols with High n-Selectivity

Schlatzer, Thomas,Schr?der, Hilmar,Trobe, Melanie,Lembacher-Fadum, Christian,Stangl, Simon,Schl?gl, Christoph,Weber, Hansj?rg,Breinbauer, Rolf

, p. 331 - 336 (2019/11/16)

The Pd-catalyzed S-allylation of thiols with stable allylcarbonate and allylacetate reagents offers several advantages over established reactions for the formation of thioethers. We could demonstrate that Pd/BIPHEPHOS is a catalyst system which allows the transition metal-catalyzed S-allylation of thiols with excellent n-regioselectivity. Mechanistic studies showed that this reaction is reversible under the applied reaction conditions. The excellent functional group tolerance of this transformation was demonstrated with a broad variety of thiol nucleophiles (18 examples) and allyl substrates (9 examples), and could even be applied for the late-stage diversification of cephalosporins, which might find application in the synthesis of new antibiotics. (Figure presented.).

Double Regioselective Asymmetric C-Allylation of Isoxazolinones: Iridium-Catalyzed N-Allylation Followed by an Aza-Cope Rearrangement

Rieckhoff, Stefan,Meisner, Jan,K?stner, Johannes,Frey, Wolfgang,Peters, René

supporting information, p. 1404 - 1408 (2018/01/01)

Isoxazolinones are biologically and synthetically interesting densely functionalized heterocycles, which for a long time were not accessible in enantioenriched form by asymmetric catalysis. Next to the deficit of enantioselective methods, the functionaliz

Rhodium-Catalyzed Asymmetric N?H Functionalization of Quinazolinones with Allenes and Allylic Carbonates: The First Enantioselective Formal Total Synthesis of (?)-Chaetominine

Zhou, Yirong,Breit, Bernhard

, p. 18156 - 18160 (2017/12/13)

An unprecedented asymmetric N?H functionalization of quinazolinones with allenes and allylic carbonates was successfully achieved by rhodium catalysis with the assistance of chiral bidentate diphosphine ligands. The high efficiency and practicality of this method was demonstrated by a low catalyst loading of 1 mol % as well as excellent chemo-, regio-, and enantioselectivities with broad functional group compatibility. Furthermore, this newly developed strategy was applied as key step in the first enantioselective formal total synthesis of (?)-chaetominine.
