Check Digit Verification of cas no

The CAS Registry Mumber 71480-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,8 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 71480-97:
(7*7)+(6*1)+(5*4)+(4*8)+(3*0)+(2*9)+(1*7)=132
132 % 10 = 2
So 71480-97-2 is a valid CAS Registry Number.

Total synthesis of (±)-decinine via an oxidative biaryl coupling with defined axial chirality

Shan, Zhen-Hua,Liu, Ji,Xu, Ling-Min,Tang, Ye-Feng,Chen, Jia-Hua,Yang, Zhen

, p. 3712 - 3715 (2012/09/21)

The total synthesis of (±)-decinine has been achieved. The key steps in the synthesis involved the formation of lasubine II via a gold catalyzed annulation of 1-(but-3-yn-1-yl)piperidine and the formation of the 12-membered ring of decinine (1) with complementary atropselectivity via a VOF 3-mediated oxidative biaryl coupling reaction.
