The CAS Registry Mumber 1049752-13-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,9,7,5 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1049752-13:
(9*1)+(8*0)+(7*4)+(6*9)+(5*7)+(4*5)+(3*2)+(2*1)+(1*3)=157
157 % 10 = 7
So 1049752-13-7 is a valid CAS Registry Number.

Synthesis of 3-aryl-4(3H)-quinazolinones from anthranilic acids and triethyl orthoformate

Cao, Sheng-Li,Zhang, Mei,Feng, Yu-Ping,Jiang, Yu-Yang,Zhang, Nan

, p. 2227 - 2236 (2008/09/21)

A one-step, convenient approach to the synthesis of 3-aryl-4(3H)- quinazolinones by the reaction of anthranilic acid with triethyl orthoformate in the presence of a catalytic amount of concentrated sulfuric acid has been developed. The possible reaction pathway was proposed. Copyright Taylor & Francis Group, LLC.
