Check Digit Verification of cas no

The CAS Registry Mumber 1190239-54-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,2,3 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1190239-54:
(9*1)+(8*1)+(7*9)+(6*0)+(5*2)+(4*3)+(3*9)+(2*5)+(1*4)=143
143 % 10 = 3
So 1190239-54-3 is a valid CAS Registry Number.

An improved synthesis of (-)-brevisamide, a marine monocyclic ether amide of dinoflagellate origin

Tsutsumi, Ryosuke,Kuranaga, Takefumi,Wright, Jeffrey L.C.,Baden, Daniel G.,Ito, Emiko,Satake, Masayuki,Tachibana, Kazuo

, p. 6775 - 6782 (2010)

An improved synthesis of (-)-brevisamide a marine cyclic ether isolated from the red-tide dinoflagellate Karenia brevis was achieved. The ether ring portion was constructed from an unsaturated lactone, which was prepared enantioselectively via an Evans aldol reaction and one-pot lactonization in the presence of excessive base after an Ando reaction. The ether ring and a dienol side chain fragment were connected via Suzuki-Miyaura coupling.

Total synthesis of brevisamide

Lee, Jihoon,Panek, James S.

supporting information; experimental part, p. 4390 - 4393 (2009/12/26)

A convergent synthesis of brevisamlde (1) is described based on the application of the crotyl silane-based [4 + 2]-annulatlon used for the preparation of the advanced oxygenated tetrahydropyran Intermediate 2. The side chain bearing a conjugated (E,E)-die
