84341-89-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84341-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,4 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84341-89:
(7*8)+(6*4)+(5*3)+(4*4)+(3*1)+(2*8)+(1*9)=139
139 % 10 = 9
So 84341-89-9 is a valid CAS Registry Number.

Application of a domino intramolecular enyne metathesis/cross metathesis reaction to the total synthesis of (+)-8-epi-xanthatin

Kummer, David A.,Brenneman, Jehrod B.,Martin, Stephen F.

, p. 4621 - 4623 (2005)

(Chemical Equation Presented) The first total synthesis of the novel sesquiterpene lactone (+)-8-epi-xanthatin (1) has been achieved starting from the commercially available ester 8. The synthesis features an asymmetric aldol reaction and palladium-catalyzed carbonylation/lactonization sequence leading to 4 and a domino ring-closing enyne metathesis/cross metathesis reaction to afford 1.
