Calculate Digit Verification of CAS Registry Number 866556-33:
(8*8)+(7*6)+(6*6)+(5*5)+(4*5)+(3*6)+(2*3)+(1*3)=214
214 % 10 = 4
So 866556-33-4 is a valid CAS Registry Number.

Synthesis of leprapinic acid, calycine and analogues by sequential "[3+2] cyclization/suzuki/lactonization" reactions

Ahmed, Zafar,Albrecht, Uwe,Langer, Peter

, p. 3469 - 3474 (2007/10/03)

Calycine and analogues were prepared on the basis of Suzuki cross-coupling reactions of γ-alkylidene-α-hydroxybutenolides - readily available by cyclization of 1,3-dicarbonyl dianions or 1,3-bis(silyl enol ether)s with oxalyl derivatives - and subsequent boron tribromide-mediated lactonization. Leprapinic acid was prepared by chemoselective boron tribromide-mediated deprotection of permethylated leprapinic acid. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
