4131-04-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4131-04-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,3 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4131-04:
(6*4)+(5*1)+(4*3)+(3*1)+(2*0)+(1*4)=48
48 % 10 = 8
So 4131-04-8 is a valid CAS Registry Number.

Hexafluoro-2-propanol-Promoted Intermolecular Friedel-Crafts Acylation Reaction

Vekariya, Rakesh H.,Aubé, Jeffrey

supporting information, p. 3534 - 3537 (2016/08/16)

The intermolecular Friedel-Crafts acylation was carried out in hexafluoro-2-propanol to yield aryl and heteroaryl ketones at room temperature without any additional reagents.

Carbonylative cross-coupling of ortho-disubstituted aryl iodides. Convenient synthesis of sterically hindered aryl ketones

Michael O'Keefe,Simmons, Nicholas,Martin, Stephen F.

supporting information; experimental part, p. 5301 - 5304 (2009/06/18)

(Chemical Equation Presented) A mild and general protocol for the carbonylative cross-coupling of sterically hindered ortho-disubstituted aryl iodides is reported. Carbonylative Suzuki-Miyaura couplings of a variety of aryl boronic acids provide an array of substituted biaryl ketones in modest to excellent yield. A carbonylative Negishi coupling that utilizes alkynyl nucleophiles is also described.
