75142-57-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75142-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,1,4 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75142-57:
(7*7)+(6*5)+(5*1)+(4*4)+(3*2)+(2*5)+(1*7)=123
123 % 10 = 3
So 75142-57-3 is a valid CAS Registry Number.

An easy access to fluoroalkanes by deoxygenative hydrofluorination of carbonyl compounds via their tosylhydrazones

Yadav, Arvind K.,Srivastava, Vishnu P.,Yadav, Lal Dhar S.

, p. 2154 - 2156 (2013/03/14)

An efficient and operationally simple synthesis of fluoroalkanes by deoxygenative hydrofluorination of carbonyl compounds via their tosylhydrazone surrogates is reported. The reaction can be carried out in a one-pot procedure directly from carbonyl compounds.

Conformational preferences of the fluoromethyl group in p-methylbenzyl fluoride and some derivatives

Schaefer, Ted,Niemczura, Walter P.,Sebastian, Rudy,Kruczynksi, Leonard J.,Danchura, Werner

, p. 1178 - 1182 (2007/10/02)

The coupling over seven bonds between 19F nuclei and protons in p-methylbenzyl fluoride and a series of ring-substituted derivatives is used to estimate the value for a conformation in which the C-F bond lies in a plane perpendicular to the benzene ring.T
