Check Digit Verification of cas no

The CAS Registry Mumber 1246973-16-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,9,7 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1246973-16:
(9*1)+(8*2)+(7*4)+(6*6)+(5*9)+(4*7)+(3*3)+(2*1)+(1*6)=179
179 % 10 = 9
So 1246973-16-9 is a valid CAS Registry Number.

Total synthesis of chivosazole F

Brodmann, Tobias,Janssen, Dominic,Kalesse, Markus

supporting information; experimental part, p. 13610 - 13611 (2010/11/17)

The first synthesis of the highly biologically active chivosazole F is described. It features an intramolecular Stille coupling for the macrolactone formation and thereby circumvents the problem of isomerization associated with the tetraene segment. Additionally, the synthesis confirms the structure which has been proposed based solely on a combination of NMR/computational methods and genetic analysis.
