Check Digit Verification of cas no

The CAS Registry Mumber 144888-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,8 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 144888-65:
(8*1)+(7*4)+(6*4)+(5*8)+(4*8)+(3*8)+(2*6)+(1*5)=173
173 % 10 = 3
So 144888-65-3 is a valid CAS Registry Number.

Unusual KF/Al2O3 Promoted Tandem Electrophilic-Nucleophilic Aromatic Substitution Leading to the Xanthone Formation

Patek, Marcel,Lebl, Michal,Budesinsky, Milos

, p. 4507 - 4508 (1992)

Formation of xanthone (III) by the KF/Al2O3 mediated O-alkylation of 2-hydroxybenzophenone (I) is described and mechanistic rationalization is proposed for this unexpected side-reaction. Key words: O-alkylation, fluoride anion, xanthone
