Calculate Digit Verification of CAS Registry Number 177079-01:
(8*1)+(7*7)+(6*7)+(5*0)+(4*7)+(3*9)+(2*0)+(1*1)=155
155 % 10 = 5

Murashima, Takashi,Uchihara, Yuki,Wakamori, Naoko,Uno, Hidemitsu,Ogawa, Takuji,Ono, Noboru

, p. 3133 - 3136 (2007/10/03)

Pyrroles fused with crown ethers are prepared by the reaction of 3,4-dihydroxy pyrrole 1 and polyethylene glycol ditosylate 2 in the presence of cesium fluoride using a convenient high dilution method. These pyrroles can be converted into the corresponding porphyrins with four crown ether moieties, which are expected to form ion channels.
