919301-81-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 919301-81-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,9,3,0 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 919301-81:
(8*9)+(7*1)+(6*9)+(5*3)+(4*0)+(3*1)+(2*8)+(1*1)=168
168 % 10 = 8
So 919301-81-8 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.
