73696-87-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73696-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,9 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73696-87:
(7*7)+(6*3)+(5*6)+(4*9)+(3*6)+(2*8)+(1*7)=174
174 % 10 = 4
So 73696-87-4 is a valid CAS Registry Number.

TOTAL SYNTHESIS OF CURZERENONE AND EPICURZERENONE

Miyashita, Masaaki,Kumazawa, Toshiaki,Yoshikoshi, Akira

, p. 593 - 596 (2007/10/02)

Curzerenone and epicurzerenone were synthesized by means of a combination of γ-ketoester synthesis and 3-methylfuran annulation both of which utilize nitroolefins as synthons.Starting material, methyl 2-methyl-4-oxo-2-vinylpentanoate, was prepared by the Lewis acid-promoted reaction of 1-methoxy-2-methyl-1--1,3-butadiene and 2-nitropropene, while key intermediate 3,6-dimethyl-6-vinyl-6,7-dihydrobenzofuran-4(5H)-one was assembled by KF-catalyzed reaction of 5-methyl-5-vinyl-cyclohexane-1,3-dione and 1-nitro-1-phenylthiopropene.
