121449-94-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121449-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,4 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121449-94:
(8*1)+(7*2)+(6*1)+(5*4)+(4*4)+(3*9)+(2*9)+(1*4)=113
113 % 10 = 3
So 121449-94-3 is a valid CAS Registry Number.

Synthesis of three marine natural sesterterpenolides from methyl isoanticopalate. First enantioselective synthesis of luffolide
Basabe,Delgado,Marcos,Diez,Diego,De Roman,Urones
, p. 9480 - 9485 (2007/10/03)
The synthesis of three marine sponge metabolites, luffolide (4), 5, and 6, are described for the first time, establishing the absolute configuration of these compounds. The key intermediate, aldehyde 17, was obtained from methyl isoanticopalate, 11. The a
