111399-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111399-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,3,9 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 111399-76:
(8*1)+(7*1)+(6*1)+(5*3)+(4*9)+(3*9)+(2*7)+(1*6)=119
119 % 10 = 9
So 111399-76-9 is a valid CAS Registry Number.

THE EPOXYHEXENYNE - VINYLFURAN TRANSFORMATION: EVIDENCE FOR CARBENE INTERMEDIATES
Eberbach, Wolfgang,Roser, Joachim
, p. 2685 - 2688 (2007/10/02)
The thermal conversion of the (Z)-epoxyhexenynes 3a/3b into three pairs of isomeric vinylfuran derivatives is explained on the basis of a multistep mechanism with butenynyl carbonyl ylides, cycloallenes and vinyl carbenes as intermediates.
