Calculate Digit Verification of CAS Registry Number 218765-79:
(8*2)+(7*1)+(6*8)+(5*7)+(4*6)+(3*5)+(2*7)+(1*9)=168
168 % 10 = 8
So 218765-79-8 is a valid CAS Registry Number.

A formal synthesis of crinipellin B based on the arene-alkene meta- photocycloaddition reaction

Wender, Paul A.,Dore, Timothy M.

, p. 8589 - 8592 (1998)

Starting from triethyl phosphonopropionate and 3-nitro-2-methylbenzoic acid, a formal synthesis of crinipellin B was achieved. The strategy draws on the use of a novel version of the arene-alkene meta-photocycloaddition reaction that proceeds with the generation of 4 rings and 4 quaternary stereocenters in one synthetic operation.
