Check Digit Verification of cas no
The CAS Registry Mumber 109300-45-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,3,0 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109300-45:
(8*1)+(7*0)+(6*9)+(5*3)+(4*0)+(3*0)+(2*4)+(1*5)=90
90 % 10 = 0
So 109300-45-0 is a valid CAS Registry Number.

A New Synthetic Route to Aromatic Gyloxals
Mahato, S. B.,Podder, G.,Maitra, S. K.
, p. 1263 (2007/10/02)
Dichloroacylation of toluene, o- and m- xylenes, chloro- and bromo-benzenes and m-chlorotoluene under Friedel-Crafts conditions leads to the corresponding chloroketones (Ia-f) which on controlled hydrolysis afford the glyoxals (IIa-f) respectively.
