63131-36-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63131-36-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,1,3 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63131-36:
(7*6)+(6*3)+(5*1)+(4*3)+(3*1)+(2*3)+(1*6)=92
92 % 10 = 2
So 63131-36-2 is a valid CAS Registry Number.

Complementing Pyridine-2,6-bis(oxazoline) with Cyclometalated N-Heterocyclic Carbene for Asymmetric Ruthenium Catalysis

Li, Long,Han, Feng,Nie, Xin,Hong, Yubiao,Ivlev, Sergei,Meggers, Eric

supporting information, p. 12392 - 12395 (2020/06/10)

A strategy for expanding the utility of chiral pyridine-2,6-bis(oxazoline) (pybox) ligands for asymmetric transition metal catalysis is introduced by adding a bidentate ligand to modulate the electronic properties and asymmetric induction. Specifically, a ruthenium(II) pybox fragment is combined with a cyclometalated N-heterocyclic carbene (NHC) ligand to generate catalysts for enantioselective transition metal nitrenoid chemistry, including ring contraction to chiral 2H-azirines (up to 97 % ee with 2000 TON) and enantioselective C(sp3)?H aminations (up to 97 % ee with 50 TON).

A copper-mediated oxidative coupling route to 3H- and 1H-indoles from N-aryl-enamines

Drouhin, Pauline,Taylor, Richard J. K.

supporting information, p. 2333 - 2336 (2015/04/22)

A facile copper(II)-mediated C-H bond oxidation and C-C bond formation procedure has been applied to the synthesis of indole derivatives. Intramolecular oxidative coupling of 3,3-disubstituted enamines proceeded using a non-expensive and air-stable copper
