338-68-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 338-68-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 338-68:
(5*3)+(4*3)+(3*8)+(2*6)+(1*8)=71
71 % 10 = 1
So 338-68-1 is a valid CAS Registry Number.

Aluminum oxide-induced gas-phase ring-opening in methyl substituted gem-difluorocyclopropanes, leading to 2-fluorobuta-1,3-dienes and vinylacetylenes

Volchkov,Lipkind,Novikov,Nefedov

, p. 658 - 663 (2015/11/27)

A gas-phase pyrolysis of methyl-substituted gem-difluorocyclopropanes in a flow-tube reactor in the presence of Al2O3 at 185 - 250 °C gives 2-fluorobuta-1,3-dienes and vinylacetylenes.
