725239-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 725239-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,5,2,3 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 725239-97:
(8*7)+(7*2)+(6*5)+(5*2)+(4*3)+(3*9)+(2*9)+(1*7)=174
174 % 10 = 4
So 725239-97-4 is a valid CAS Registry Number.

Efficient and Z-selective cross-metathesis of conjugated enynes
Hansen, Eric C.,Lee, Daesung
, p. 2035 - 2038 (2007/10/03)
Equation presented. The generation of a conjugated alkynyl alkylidene has been achieved using an allyl ether moiety as an intramolecular catalyst delivery vehicle. The reaction of this intermediate with alkenes and alkynes yields conjugated enynes with Z-
