Check Digit Verification of cas no

The CAS Registry Mumber 126403-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,4,0 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126403-71:
(8*1)+(7*2)+(6*6)+(5*4)+(4*0)+(3*3)+(2*7)+(1*1)=102
102 % 10 = 2
So 126403-71-2 is a valid CAS Registry Number.

Sequential Organozinc Formation and Negishi Cross-Coupling of Amides Catalysed by Cobalt Salt

Dorval, Céline,Dubois, Elodie,Bourne-Branchu, Yann,Gosmini, Corinne,Danoun, Grégory

supporting information, p. 1777 - 1780 (2019/02/26)

Herein, a cobalt-catalysed Negishi-type cross-coupling of amide derivatives is described. Apart from being the first example of cobalt-catalysed Negishi-type coupling of amides, the process described employs a unique, simple, and cheap catalytic system to perform both the organozinc formation and the Negishi-type coupling. Indeed, the same cobalt(II) bromide salt used to form the arylzinc species from aryl bromides is then re-used to perform the cross coupling of this resulting arylzinc with N-benzoyl glutarimides at room temperature. The main advantages of the reaction presented are its robustness and ease of use. Indeed, the reactions of organozinc formation and Negishi-type coupling are performed without precautions toward water or oxygen. (Figure presented.).

One-pot synthesis of aryl sulfones from organometallic reagents and iodonium salts

Margraf, Natalie,Manolikakes, Georg

, p. 2582 - 2600 (2015/03/18)

A transition-metal-free arylation of lithium, magnesium, and zinc sulfinates with diaryliodonium salts is described. The sulfinic acid salts were prepared from the reaction of the corresponding organometallic reagents and sulfur dioxide. Combination of the three single steps (preparation of the organometallic compound, sulfinate formation, and arylation) leads to a one-pot sequence for the synthesis of aryl sulfones from simple starting materials. The chemoselectivity of unsymmetrical diaryliodonium salts has been investigated. Potential and limitations of this method will be discussed.

Nickel-catalyzed enantioselective arylation of pyridinium ions: Harnessing an iminium ion activation mode

Chau, Stephen T.,Lutz, J. Patrick,Wu, Kevin,Doyle, Abigail G.

supporting information, p. 9153 - 9156 (2013/09/12)

A nickel for your thoughts.?? An enantioselective nickel-catalyzed cross-coupling between N-acylpyridinium salts and organozinc reagents is reported. The catalytic system, which is comprised of an air-stable NiII source and a chiral phosphoramidite ligand, affords 2-substituted-2,3-dihydro-4-pyridones with up to >99 % ee. Copyright
