1304513-59-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1304513-59-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,5,1 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1304513-59:
(9*1)+(8*3)+(7*0)+(6*4)+(5*5)+(4*1)+(3*3)+(2*5)+(1*9)=114
114 % 10 = 4
So 1304513-59-4 is a valid CAS Registry Number.

An acid-catalysed conversion of 2-(4-quinazolinylamino)benzoic acid into 2-(2-aminophenyl)-4(1 H)-quinazolinone
Sneddon, Helen F.,Lynn, Sean M.
, p. 573 - 575 (2011)
An acid-catalysed conversion of N-arylcarboxy-4-quinazolinones into 2-(2-aminoaryl)-4(1H)-quinazolinones has been observed. This reaction allows for a nucleophilic aromatic substitution reaction between aminobenzoic acids and 4-chloroquinazolines to form
