Check Digit Verification of cas no
The CAS Registry Mumber 2525-07-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,2 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2525-07:
(6*2)+(5*5)+(4*2)+(3*5)+(2*0)+(1*7)=67
67 % 10 = 7
So 2525-07-7 is a valid CAS Registry Number.

4'-tert-AlkylbenzoCrown-5-Ether. Syntheses and Complexes with Potassium Thiocyanate
Beger, J.,Meerbote, M.
, p. 2 - 9 (2007/10/02)
The title compounds 4 are synthesized either by alkylation of pyrocatechole 1 in 4-position and followed by ring closure with 1,11-dichloro-3,6,9-trioxaundecane or by alkylation of benzo-crown-5 3.In most cases the way first mentioned gives better results.Analytical samples of the alkylated benzocrown-5 ethers 4 are obtained through complexing with KSCN.Physical data and 1H-n.m.r.-spectra of 5 new pyrocatecholes 2 and 6 new benzocrown-5 ethers 4 are given.
