Check Digit Verification of cas no

The CAS Registry Mumber 344771-27-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,7,7 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 344771-27:
(8*3)+(7*4)+(6*4)+(5*7)+(4*7)+(3*1)+(2*2)+(1*7)=153
153 % 10 = 3
So 344771-27-3 is a valid CAS Registry Number.

TRANSFORMATION OF cis-ENYNE-SUBSTITUTED OXIRANES TO 2-VINYLFURANS SEVEN-MEMBERED CYCLOALLENES AS INTERMEDIATES ?

Roser, Joachim,Eberbach, Wolfgang

, p. 2455 - 2458 (2007/10/02)

Upon thermal activation the 1,2-epoxy-(Z)-3-hexen-5-ynes 5a-c are transformed predominantly into the 2-vinylfurans 9a-c/10a-c.A reaction mechanism is proposed which involves the transformation of 7-membered cycloallenes (structure 3) as central intermediates.
