Check Digit Verification of cas no

The CAS Registry Mumber 58426-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,4,2 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58426-39:
(7*5)+(6*8)+(5*4)+(4*2)+(3*6)+(2*3)+(1*9)=144
144 % 10 = 4
So 58426-39-4 is a valid CAS Registry Number.

Preparation of 4(3H)-quinazolinones from aryldiazonium salt, nitriles and 2-aminobenzoate via a cascade annulation

Ramanathan, Mani,Hsu, Ming-Tsung,Liu, Shiuh-Tzung

, p. 791 - 796 (2019)

One-pot synthesis of 3-aryl-4(3H)-quinazolinones has been realized through a cascade annulation. Reaction of aryldiazonium salt with a nitrile provides in situ generation of a reactive nitrilium ion, which is attacked by the amino group of 2-aminobenzoate followed by cyclization to deliver the desired product. This strategy offers a convenient and easy access to a wide range of functionalized quinazolinone.
