Check Digit Verification of cas no

The CAS Registry Mumber 1126975-09-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,6,9,7 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1126975-09:
(9*1)+(8*1)+(7*2)+(6*6)+(5*9)+(4*7)+(3*5)+(2*0)+(1*9)=164
164 % 10 = 4
So 1126975-09-4 is a valid CAS Registry Number.

Antineoplastic agents. 571. total synthesis of bacillistatin 2

Pettit, George R.,Hu, Shougang,Knight, John C.,Chapuis, Jean-Charles

, p. 372 - 379 (2009)

The first total synthesis of bacillistain 2 (2) has been achieved in 24 steps and 22.9% overall yield, providing a quite efficient route with maximal convergence. Notable features of this approach include two successful applications of the Mitsunobu reaction during respective assemblies of key intermediates 22 and 27, successful employment of 2-methyl- 6-nitrobenzoic anhydride (MNBA) in the formation by lactonization of a macrocyclic (36-membered) ring, and very flexible access to structural modifications of the bacillistatin-type cyclodepsipeptides.
