Calculate Digit Verification of CAS Registry Number 132891-38:
(8*1)+(7*3)+(6*2)+(5*8)+(4*9)+(3*1)+(2*3)+(1*8)=134
134 % 10 = 4
So 132891-38-4 is a valid CAS Registry Number.

Intramolecular SH2 macrocyclisations

Baldwin, Jack E.,Adlington, Robert M.,Mitchell, Mark B.,Robertson, Jeremy

, p. 5901 - 5918 (2007/10/02)

The synthesis of 10-15 membered α-methylene macrocyclic lactones from the functionalised allylstannanes (7e)-(7j) is described. Attempts to synthesise analogous 6-9 membered lactones proved unsuccessful, resulting instead in the production of dilactones and AIBN derived adducts.
