Check Digit Verification of cas no

The CAS Registry Mumber 149683-62-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,6,8 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 149683-62:
(8*1)+(7*4)+(6*9)+(5*6)+(4*8)+(3*3)+(2*6)+(1*2)=175
175 % 10 = 5
So 149683-62-5 is a valid CAS Registry Number.

A NEW METHOD FOR THE ELECTROPHILIC FLUORINATION OF VINYL STANNANES.

Matthews, Donald P.,Miller, Shawn C.,Jarvi, Esa T.,Sabol, Jeffrey S.,McCarthy, James R.

, p. 3057 - 3060 (1993)

A new method for the electrophilic fluorination of vinyl stannanes using commercially available 1-chloromethyl-4-fluoro-1,4-diazoniabicyclooctane bis(tetrafluoroborate) (1) has been developed.

New methodology for the deoxygenative difluoromethylenation of aldehydes and ketones; unexpected formation of tetrafluorocyclopropanes

Nowak, Ireneusz,Robins, Morris J.

, p. 721 - 724 (2005)

(Chemical Equation Presented) Generation of difluoromethylene phosphorus ylides in the presence of aldehydes and ketones results in Wittig-type reactions to give gem-difluoroalkenes. Subsequent in situ addition of difluorocarbene (carbenoid) can occur (in

Difluoromethyl 2-pyridyl sulfone: A new gem-difluoroolefination reagent for aldehydes and ketones

Zhao, Yanchuan,Huang, Weizhou,Zhu, Lingui,Hu, Jinbo

supporting information; experimental part, p. 1444 - 1447 (2010/06/20)

Chemical equation presented Difluoromethyl 2-pyridyl sulfone, a previously unknown compound, was found to act as a novel and efficient gem-difluoroolefination reagent for both aldehydes and ketones. It was found that the fluorinated sulfinate intermediate in the reaction is relatively stable, which can be observed by 19F NMR and trapped with CH 3l.
