Check Digit Verification of cas no

The CAS Registry Mumber 2688-95-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2688-95:
(6*2)+(5*6)+(4*8)+(3*8)+(2*9)+(1*5)=121
121 % 10 = 1
So 2688-95-1 is a valid CAS Registry Number.

Nucleophilic substitution in O-phenyldibenzofuranium and 10-phenylxanthonium cations

Tolstaya,Bobyleva,Vanchikov,Kovalysheva,Kulikov,Tsariev

, p. 789 - 797 (2007/10/03)

Reactions of O-phenyldibenzofuranium tetrafluoroborate with nucleophiles (OH-, NO2-, AcO-) in aqueous media follow the SNAr-mechanism and involve dehydroarenes. In DMSO, this salt smoothly reacts with NO2- and I- with predominant opening of the furan ring. 10-Phenylxanthonium tetrafluoroborate readily arylates the NO2- ion in water (at the N and O atoms), mainly with predominant opening of the central ring, and is completely decomposed even with weak bases (NH2OH, 2,4-dinitrophenylhydrazine). The Baeyer -Villiger oxidation of this salt affords xanthone and 2-phenoxybenzoic acid.
