Check Digit Verification of cas no

The CAS Registry Mumber 1191384-99-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,3,8 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1191384-99:
(9*1)+(8*1)+(7*9)+(6*1)+(5*3)+(4*8)+(3*4)+(2*9)+(1*9)=172
172 % 10 = 2
So 1191384-99-2 is a valid CAS Registry Number.

Synthesis of the monomeric counterpart of marinomycin A

Amans, Dominique,Bareille, Laurianne,Bellosta, Veronique,Cossy, Janine

, p. 7665 - 7674 (2009)

(Chemical Equation Presented) An efficient and highly convergent synthesis of the monomeric counterpart of the antitumor-antibiotic marine natural product marinomycin A was achieved by using optically active titanium complexes to control the configuration of the stereogenic centers, a highly stereo- and regioselective cross-metathesis to generate the (E)-configured C20-C21 double bond, and a Horner-Wadsworth-Emmons olefination followed by a Pd-catalyzed Stille cross-coupling to construct the tetraene moiety.
