Check Digit Verification of cas no
The CAS Registry Mumber 15222-53-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,2 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15222-53:
(7*1)+(6*5)+(5*2)+(4*2)+(3*2)+(2*5)+(1*3)=74
74 % 10 = 4
So 15222-53-4 is a valid CAS Registry Number.

Depsidone Synthesis. Part 21. A New Synthesis of Grisa-2',5'-diene-3,4'-diones
Sargent, Melvyn V.
, p. 403 - 411 (2007/10/02)
Treatment of suitably substituted methyl 2-phenoxybenzoates with titanium(IV) chloride and dry hydrogen chloride afforded grisa-2',5'-diene-3,4'-diones in high yield.The structures of these compounds followed from their thermal stability, their methanolysis to methyl 2-(4-hydroxyphenoxy)benzoates, and their reductive cleavage to 2,4'-dihydrobenzophenones.Treatment of the benzophenones with base gave xanthones.An attempt to synthesize dehydrogriseofulvin (1) by this method failed.
