Check Digit Verification of cas no

The CAS Registry Mumber 33168-14-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,6 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33168-14:
(7*3)+(6*3)+(5*1)+(4*6)+(3*8)+(2*1)+(1*4)=98
98 % 10 = 8
So 33168-14-8 is a valid CAS Registry Number.

Synthesis of alkyl-aryl ethers by copper-catalyzed etherization reactions of aryl fluorides with tetraalkylammonium bromides and H2O

Wang, Feng,Tang, Boxiao,Xie, Yexiang,Li, Jinheng

, p. 2318 - 2322 (2010)

Synthesis of alkyl aryl ethers via copper-catalyzed etherizations of electron-deficient aryl fluorides with quaternary ammonium bromides and water has been developed. In the presence of Cu(OAc)2, POPh3 (L4) and Cs2CO3, a variety of electron-deficient aryl fluorides underwent the reaction with quaternary ammonium bromides and H 2O in moderate to good yields. The mechanism was also discussed.
