82613-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82613-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,6,1 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82613-16:
(7*8)+(6*2)+(5*6)+(4*1)+(3*3)+(2*1)+(1*6)=119
119 % 10 = 9
So 82613-16-9 is a valid CAS Registry Number.

Selective Monodemethylation of 2,4-Dimethoxyquinolines: A General Synthesis of 2-Quinolones
Joag, Sushama D.
, p. 238 - 239 (2007/10/02)
4,6-Dimethoxy-2-quinolone (1a), 4-methoxy-6,7-methylenedioxy-2-quinolone (1b) and 4-methoxy-8-hydroxy-2-quinolone (1c) are obtained in high yields from the corresponding 2,4-dimethoxyquinolines on refluxing with acetic acid.
