2266-53-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2266-53-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,6 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2266-53:
(6*2)+(5*2)+(4*6)+(3*6)+(2*5)+(1*3)=77
77 % 10 = 7
So 2266-53-7 is a valid CAS Registry Number.

Accelerating influence of the gem-difluoromethylene group in a ring-closing olefin metathesis reaction. A Thorpe-Ingold effect?

Urbina-Blanco, Cesar A.,Skibinski, Maciej,O'Hagan, David,Nolan, Steven P.

supporting information, p. 7201 - 7203 (2013/08/15)

The gem-difluoromethylene (CF2) group significantly accelerates ring-closing metathesis of 1,8-nonadienes relative to the methylene (CH 2) group demonstrating similar rate accelerations to that observed for the classic Thorpe-Ingold substituents, diester malonates and ketals.

Mechanistic aspects of the fluorination of cyclohexane and cyclohexene with acetyl hypofluorite in acetic acid

Visser, G. W. M.,Bakker, C. N. M.,Halteren, R. W. v.,Herscheld, J. D. M.,Brinkman, G. A.,Hoekstra, A.

, p. 214 - 219 (2007/10/02)

The reaction of acetyl hypofluorite in acetic acid with both cyclohexane and cyclohexene has been investigated.Analysis by GCMS and radio-HPLC, using (18)F as a tracer, revealed that apart from typical products expected from a radical reaction, several compounds originating from carbocationic intermediates were formed.On the basis of the observed products, a single-electrontransfer (SET) mechanism leading to an intermediate radical-cation is proposed.
