207302-96-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 207302-96-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,3,0 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 207302-96:
(8*2)+(7*0)+(6*7)+(5*3)+(4*0)+(3*2)+(2*9)+(1*6)=103
103 % 10 = 3
So 207302-96-3 is a valid CAS Registry Number.

Synthetic studies of antitumor macrolide rhizoxin: Stereoselective syntheses of the C(1)-C(9) and C(12)-C(26) subunits

Burke, Steven D.,Hong, Jian,Lennox, Joseph R.,Mongin, Andrew P.

, p. 6952 - 6967 (2007/10/03)

A triply convergent synthetic approach which culminates in the enantioselective syntheses of the C(1)-C(9) and C(12)-C(26) subunits of the macrolide antitumor agent rhizoxin is described. The central C(12)-C(20) subunit 4 has been prepared efficiently via diastereoselective enzymatic acetate hydrolysis of 15 with porcine pancreatic lipase, a chelation- controlled Ireland-Claisen rearrangement (10 → 12) combined with kinetic bromolactonization (12 → 14), and Mitsunobu inversion (23 → 26) to introduce the three contiguous C(15)-C(17) stereocenters. Formation of the C(18)-C(19) trisubstituted (E)-olefin was achieved by a stereoselective Horner-Wadsworth-Emmons reaction. The central segment 4 and the oxazole chromophore side chain 3 were coupled using another highly stereoselective Horner-Wadsworth-Emmons reaction. Two different lactone subunits [C(1)-C(9) segment 5 and C(3)-C(10) segment 47] were also prepared, employing a thermodynamically controlled diastereotopic group differentiation tactic for establishing the C(5) stereochemistry.
