Check Digit Verification of cas no
The CAS Registry Mumber 35031-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,0,3 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 35031-72:
(7*3)+(6*5)+(5*0)+(4*3)+(3*1)+(2*7)+(1*2)=82
82 % 10 = 2
So 35031-72-2 is a valid CAS Registry Number.

Catalytic Friedel-Crafts acylation of alkoxybenzenes mediated by aluminum hydrogensulfate in solution and solvent-free conditions

, p. 1863 - 1864 (2007/10/03)
Friedel-Crafts acylation of alkoxybenzenes was achieved efficiently by a reaction with aliphatic acid anhydrides in the presence of catalytic amounts of aluminum hydrogensulfate, Al(HSO4)3, in nitromethane and under solvent-free conditions. Alkylbenzenes and aryl halides, as well as aromatic anhydrides, remained intact under these conditions.
