Check Digit Verification of cas no

The CAS Registry Mumber 1040908-34-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,9,0 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1040908-34:
(9*1)+(8*0)+(7*4)+(6*0)+(5*9)+(4*0)+(3*8)+(2*3)+(1*4)=116
116 % 10 = 6
So 1040908-34-6 is a valid CAS Registry Number.

Reversible modulation of the activity of thiourea catalysts with anions: A simple approach to switchable asymmetric catalysis

Foli, Giacomo,D'Elia, Cecilia Sasso,Fochi, Mariafrancesca,Bernardi, Luca

, p. 66490 - 66494 (2016)

Leveraging the anion binding properties of thioureas, we show that the activity of known well-performing chiral catalysts can be reduced by coordinating anions (e.g. chloride) and restored by anion metatheses. Three benchmark enantioselective transformati

Exploiting the chiral ligands of bis(Imidazolinyl)-and bis(oxazolinyl)thiophenes—Synthesis and application in Cu-catalyzed friedel–crafts asymmetric alkylation

Al-Majid, Abdullah Mohammed,Alammari, Abdullah Saleh,Alshahrani, Saeed,Barakat, Assem,Haukka, Matti,Islam, Mohammad Shahidul

, (2021/12/17)

Five new C2-symmetric chiral ligands of 2,5-bis(imidazolinyl)thiophene (L1–L3) and 2,5-bis(oxazolinyl)thiophene (L4 and L5) were synthesized from thiophene-2,5-dicarboxylic acid (1) with enantiopure amino alcohols (4a–c) in excellent optical purity and chemical yield. The util-ity of these new chiral ligands for Friedel–Crafts asymmetric alkylation was explored. Subse-quently, the optimized tridentate ligand L5 and Cu(OTf)2 catalyst (15 mol%) in toluene for 48 h promoted Friedel–Crafts asymmetric alkylation in moderate to good yields (up to 76%) and with good enantioselectivity (up to 81% ee). The bis(oxazolinyl)thiophene ligands were more potent than bis(imidazolinyl)thiophene analogues for the asymmetric induction of the Friedel–Crafts asymmetric alkylation.

Rhodium-catalyzed asymmetric addition of arylboronic acids to indolylnitroalkenes

Xing, Junwei,Chen, Guihua,Cao, Peng,Liao, Jian

, p. 1230 - 1236 (2012/04/10)

Indolylnitroethanes and their derivatives are key intermediates to many bioactive structures. Most approaches to access chiral indolylnitroethanes involve organocatalyzed or metal-catalyzed asymmetric Friedel-Crafts reaction of indoles with nitroalkenes.

Chiral phosphoric acid catalyzed enantioselective Friedel-Crafts alkylation of indoles with nitroalkenes: Cooperative effect of 3 A molecular sieves

Itoh, Junji,Fuchibe, Kohei,Akiyama, Takahiko

supporting information; experimental part, p. 4016 - 4018 (2009/02/08)

(Chemical Equation Presented) Crafty catalysts: Friedel-Crafts alkylation of indoles with nitroalkenes proceeded in the presence of phosphoric acid 1 and 3 A molecular sieves to give Friedel-Crafts adducts with excellent enantioselectivities (see scheme).
