116707-98-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116707-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,7,0 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 116707-98:
(8*1)+(7*1)+(6*6)+(5*7)+(4*0)+(3*7)+(2*9)+(1*8)=133
133 % 10 = 3
So 116707-98-3 is a valid CAS Registry Number.

Rh-Catalyzed Domino Addition-Enolate Arylation: Generation of 3-Substituted Oxindoles via a Rh(lll) Intermediate

Jang, Young Jin,Yoon, Hyung,Lautens, Mark

supporting information, p. 3895 - 3897 (2015/08/18)

A Rh-catalyzed domino conjugate addition-arylation sequence via a Rh(III) intermediate is reported. This process involving a proposed intramolecular oxidative addition of a rhodium enolate was utilized to achieve the synthesis of 3-substituted oxindole derivatives in moderate to excellent yields.

Indirect Electroreductive Cyclisation of N-Allylic and N-Propargylbromo Amides and o-Bromoacryloylanilides using Nickel(II) Complexes as Electron-transfer Catalysts

Ozaki, Shigeko,Matsushita, Hidenori,Ohmori, Hidenobu

, p. 2339 - 2344 (2007/10/02)

Nickel(II) complex-catalysed indirect electroreduction of N-allylic and N-propargyl-α-bromo amides and o-bromoacryloylanilides gave the corresponding 5-membered lactams.The product distribution was affected by the ability of the solvent to donate hydrogen atom.The electroreduction of N-allyl-N-(bromoacetyl)toluene-p-sulfonamide 1a in DMF and acetonitrile yielded as main product the 4-methylpyrrolidinone 2a (41percent) and the 4-(bromomethyl)pyrrolidinone 3a (33percent), respectively.On addition of 2 mol equiv. of a hydrogen-atom donor (Ph2PH) to the reaction of bromo amide 1a in acetonitrile, compound 1a provided compound 2a (58percent) as the sole cylised product.
