The CAS Registry Mumber 104429-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,2 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104429-39:
(8*1)+(7*0)+(6*4)+(5*4)+(4*2)+(3*9)+(2*3)+(1*9)=102
102 % 10 = 2
So 104429-39-2 is a valid CAS Registry Number.

STEREOSELECTIVE SYNTHESIS AND THERMAL BEHAVIOR OF (Z)-EPOXYHEXENYNES: A SIMPLE AND GENERAL ROUTE TO 2-VINYLFURANS

Eberbach, Wolfgang,Roser, Joachim

, p. 2797 - 2802 (2007/10/02)

An efficient approach for the synthesis of 2,3-disubstituted furans (2a-j/3a-j) is described by using the thermally induced rearrangement of epoxyhexenynes (1a-j) which are prepared by streoselective synthesis of the (Z)-pentenynals 10 and subsequent Darz
