107743-12-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107743-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,7,4 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 107743-12:
(8*1)+(7*0)+(6*7)+(5*7)+(4*4)+(3*3)+(2*1)+(1*2)=114
114 % 10 = 4
So 107743-12-4 is a valid CAS Registry Number.

Activating Unreactive Sites of Organic Molecules Using Elemental Fluorine
Rozen, Shlomo,Gal, Chava
, p. 2769 - 2779 (2007/10/02)
Electrophilic substitution reactions on saturated carbons are extremely rare.Elemental fluorine, however, uses this pathway to replace tertiary unactivated hydrogens with great regio- and stereoselectivity, resulting in a full retention of configuration.I
