73407-87-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73407-87-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,0 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73407-87:
(7*7)+(6*3)+(5*4)+(4*0)+(3*7)+(2*8)+(1*7)=131
131 % 10 = 1
So 73407-87-1 is a valid CAS Registry Number.

Helenanolides: Stereocontrolled Total Synthesis of dl-Bigelovin, dl-Mexicanin I, and dl-Linifolin A

Grieco, Paul A.,Ohfune, Yasufumi,Majetich, George F.

, p. 360 - 366 (2007/10/02)

Stereocontrolled total syntheses of the sesquiterpene lactones dl-bigelovin (11), dl-mexicanin I (12), and dl-linifolin A (13) are described.The syntheses start with the hydroazulenone 4 and proceed via the key epoxy alkohol 9.Elaboration of 9 into the tricyclic γ-lactone 14 dl-bigelovin. α-methylenation.Subsequent oxidation at C(4) completes the synthesis of dl-bigelovin.Epoxide opening of 9 with dilithioacetate provides access to tricyclic lactone 23 which gives way to 24 via reduction of ketone 25.Cleavage of the benzyl ether in 24 followed by α-methylenationand oxidation generates dl-mexicanin I.Acetylation of 12 affords dl-linifolin A.
