Calculate Digit Verification of CAS Registry Number 1197850-85:
(9*1)+(8*1)+(7*9)+(6*7)+(5*8)+(4*5)+(3*0)+(2*8)+(1*5)=203
203 % 10 = 3
So 1197850-85-3 is a valid CAS Registry Number.

Enantioselective total synthesis of (-)-laurenditerpenol

Pitsinos, Emmanuel N.,Athinaios, Nikolaos,Vidali, Veroniki P.

supporting information, p. 4666 - 4669 (2012/10/30)

A highly convergent total synthesis of (-)-laurenditerpenol has been accomplished through an organolithium to aldehyde nucleophilic addition. Preparation of the prerequisite key intermediates in optically pure form was based on an improved, short, and efficient synthesis of wine lactone from (S)-limonene and Corey's catalytic enantioselective Diels-Alder reaction of 2,5-dimethyl furan with diethyl fumarate.
