Check Digit Verification of cas no

The CAS Registry Mumber 137937-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,3 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137937-39:
(8*1)+(7*3)+(6*7)+(5*9)+(4*3)+(3*7)+(2*3)+(1*9)=164
164 % 10 = 4
So 137937-39-4 is a valid CAS Registry Number.

Selectivity in the photo-Fries reaction of phenyl phenylacetates included in a nation membrane

Tung, Chen-Ho,Xu, Xiao-He

, p. 127 - 130 (2007/10/03)

Photoirradiation of phenyl phenylacetates included within a Nafion membrane exclusively resulted in ortho-hydroxyphenones, thus achieving high selectivity in the photo-Fries reaction.

A REEXAMINATION OF THE RETRO-FRIES REARRANGEMENT OF SOME o-HYDROXYKETONES

Martin, Robert,Lafrance, Jean Ronald,Demerseman, Pierre

, p. 539 - 548 (2007/10/02)

The retro-Fries rearrangement, catalyzed by protic and Lewis acids, was studied for some o-hydroxyketones.The results are consistent with the mechanism of an heterolytic cleavage and rearrangement.It appears that, in general, Lewis acids do not induce the retro-Fries rearrangement of o-hydroxyketones.However, in certain cases, it may be brought about the presence of a protic acid generated in situ, from a solvent-catalyst interaction.
