109300-46-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109300-46-1 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 109300-46:
(8*1)+(7*0)+(6*9)+(5*3)+(4*0)+(3*0)+(2*4)+(1*6)=91
91 % 10 = 1
So 109300-46-1 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.
