Check Digit Verification of cas no

The CAS Registry Mumber 570394-38-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,0,3,9 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 570394-38:
(8*5)+(7*7)+(6*0)+(5*3)+(4*9)+(3*4)+(2*3)+(1*8)=166
166 % 10 = 6
So 570394-38-6 is a valid CAS Registry Number.

Directed hydrogenations and an Ireland-Claisen rearrangement linked to Evans-Tishchenko chemistry: The highly efficient total synthesis of the marine cyclodepsipeptide doliculide

Chen, Tao,Altmann, Karl-Heinz

, p. 8403 - 8407 (2015)

Two new convergent total syntheses have been developed for the cytotoxic, actin microfilament-stabilizing marine cyclodepsipeptide doliculide (1). A key strategic element of both routes is the establishment of the central stereogenic center of the characteristic polydeoxypropionate stereotriad by means of a hydroxyl-directed catalytic hydrogenation of a trisubstituted double bond. The requisite olefin substrates were obtained through a modified Suzuki-Miyaura coupling or through Ireland-Claisen rearrangement of a propionate ester, respectively; the latter was the direct result of a highly selective Evans-Tishchenko reduction of a hydroxy ketone that had been obtained in a stereoselective Paterson aldol reaction. Doliculide (1) was finally obtained in a total number of 17 or 15 (14) linear steps, respectively, which represents a substantial improvement over previous syntheses of this highly bioactive natural product.

The synthesis of deoxyfusapyrone. 2. Preparation of the bis-trisubstituted olefin fragment and its attachment to the pyrone moiety

Organ, Michael G.,Wang, Junquan

, p. 5568 - 5574 (2007/10/03)

A convergent and modular synthesis has been devised to construct the eight diastereoisomers of deoxyfusapyrone (1). In this paper the synthesis of the complex polyene chain is reported as is its connection to the pyrone moiety that is in the middle of the
