Check Digit Verification of cas no

The CAS Registry Mumber 1374410-01-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,4,1 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1374410-01:
(9*1)+(8*3)+(7*7)+(6*4)+(5*4)+(4*1)+(3*0)+(2*0)+(1*1)=131
131 % 10 = 1
So 1374410-01-1 is a valid CAS Registry Number.

Total syntheses of anominine and tubingensin A

Bian, Ming,Wang, Zhen,Xiong, Xiaochun,Sun, Yu,Matera, Carlo,Nicolaou,Li, Ang

, p. 8078 - 8081 (2012)

A divergent strategy for the total syntheses of the indole terpenoid anominine (1) and its natural congener tubingensin A (2) has been developed. The common intermediate 11 bearing all of the required stereogenic centers for both natural products was first assembled by employing a Ueno-Stork radical cyclization and a Sc(OTf)3-mediated Mukaiyama aldol reaction to form the key C-C bonds in a stereocontrolled manner. The route to anominine features a radical deoxygenation followed by an efficient side-chain installation, while the path to tubingensin A exploits a CuOTf-promoted 6π-electrocyclization/ aromatization sequence to forge the central region of the pentacyclic scaffold.
