Calculate Digit Verification of CAS Registry Number 68423-36:
(7*6)+(6*8)+(5*4)+(4*2)+(3*3)+(2*3)+(1*6)=139
139 % 10 = 9
So 68423-36-9 is a valid CAS Registry Number.

Synthesis of Ether Oligomers

Renaudet, Olivier,Reymond, Jean-Louis

, p. 397 - 400 (2007/10/03)

(Equation presented) Hydroxyaromatic aldehydes and ketones were used as building blocks to prepare ether oligomers. An iterative two-step protocol involving Mitsunobu coupling and carbonyl reduction provided a protecting-group-free route with high yields. Activity screening of an 84-member library against proteases led to the discovery of micromolar inhibitors for trypsin, chymotrypsin, and subtilisin.
