Calculate Digit Verification of CAS Registry Number 344765-69:
(8*3)+(7*4)+(6*4)+(5*7)+(4*6)+(3*5)+(2*6)+(1*9)=171
171 % 10 = 1
So 344765-69-1 is a valid CAS Registry Number.

Tandem ring-closing metathesis-radical cyclization based on 4-(phenylseleno)butanal and methyl 3-(phenylseleno)propanoate - A route to bicyclic compounds

Clive,Cheng

, p. 605 - 606 (2007/10/03)

α,ω-(Phenylseleno) carbonyl compounds, such as 4-(phenylseleno)butanal (1) and methyl 3-(phenylseleno)propanoate (2), are easily converted by anionic reactions into substances that undergo sequential ring-closing metathesis and radical cyclization, affording bicyclic products.
