Calculate Digit Verification of CAS Registry Number 669083-85:
(8*6)+(7*6)+(6*9)+(5*0)+(4*8)+(3*3)+(2*8)+(1*5)=206
206 % 10 = 6

Huge (14-, 21-, 28-, 35-, 56- and 70-membered ring) macrocyclic lactams - A novel family of carbopeptoid-cyclodextrins

Mayes, Benjamin A.,Simon, Lieven,Watkin, David J.,Ansell, Christopher W. G.,Fleet, George W. J.

, p. 157 - 162 (2004)

Hydrogenation of linear ω-azido-pentafluorophenyl esters gives cyclic peptides containing 14-, 21-, 28-, 35-, 56- and 70-membered ring lactams from oligomers derived from ε-amino acids in excellent to moderate yields with a lack of racemisation during the cyclisation step.
