Calculate Digit Verification of CAS Registry Number 179129-22:
(8*1)+(7*7)+(6*9)+(5*1)+(4*2)+(3*9)+(2*2)+(1*2)=157
157 % 10 = 7
So 179129-22-7 is a valid CAS Registry Number.

Synthesis of 5-/10-membered ring analogues of the dienediyne core of neocarzinostatine chromophore by palladium(0)-mediated ring-closure reaction

Suffert, Jean,Abraham, Estelle,Raeppel, Stephane,Brueckner, Reinhard

, p. 447 - 456 (2007/10/03)

The new dienediynes 5, 6, and 7 were synthesised from a monoprotected diyne and an already described bis(enol triflate) 4 derived from formylcyclopentanone. When 5 and 6 were subjected to nucleophilic attack by a thiol, cycloaromatisation occurred, and the phenanthrenes 23a and 23b were obtained in 30 and 42% yield, respectively.
