640298-47-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 640298-47-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,9 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 640298-47:
(8*6)+(7*4)+(6*0)+(5*2)+(4*9)+(3*8)+(2*4)+(1*7)=161
161 % 10 = 1
So 640298-47-1 is a valid CAS Registry Number.

Total synthesis of (+)-aspergillide C

Kanematsu, Makoto,Yoshida, Masahiro,Shishido, Kozo

scheme or table, p. 1372 - 1374 (2011/03/21)

The enantioselective total synthesis of aspergillide C, a member of a novel class of 14-membered macrolides isolated from the marine-derived fungus Aspergillus ostianus strain 01F313, has been accomplished employing a highly diastereoselective intramolecu

Total synthesis of (R)-(+)-goniothalamin and (R)-(+)-goniothalamin oxide: first application of the sulfoxide-modified Julia olefination in total synthesis

Pospí?il, Ji?í,Markó, István E.

, p. 5933 - 5937 (2007/10/03)

A short and efficient synthesis of (R)-(+)-goniothalamin 1 and (R)-(+)-goniothalamin oxide 2 is described. During this approach, the sulfoxide-modified Julia olefination was used as a key step to connect aldehyde 5 to sulfoxide 6. The desired styryl-containing adduct is obtained in good yield and with excellent E/Z selectivity.
