Calculate Digit Verification of CAS Registry Number 68432-82:
(7*6)+(6*8)+(5*4)+(4*3)+(3*2)+(2*8)+(1*2)=146
146 % 10 = 6
So 68432-82-6 is a valid CAS Registry Number.

First total synthesis of tenuifolin via PIFA mediated oxidative biaryl coupling

Tang, Changhua,Li, Ziyuan,Wang, Yiyun,Xu, Jinyi,Kong, Lingyi,Yao, Hequan,Wu, Xiaoming

, p. 3275 - 3278 (2011)

The first total synthesis of a sesquiterpenoid, tenuifolin, was achieved in seven linear steps. Phenyliodine(III) bis(trifluoacetate) (PIFA) mediated oxidative biaryl coupling was employed as a key step to construct the central seven-membered ring with a double bond. The double bond formation was also exploited.
