Check Digit Verification of cas no

The CAS Registry Mumber 108047-38-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,0,4 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 108047-38:
(8*1)+(7*0)+(6*8)+(5*0)+(4*4)+(3*7)+(2*3)+(1*8)=107
107 % 10 = 7
So 108047-38-7 is a valid CAS Registry Number.

Base-Promoted Synthesis of 2-Aryl Quinazolines from 2-Aminobenzylamines in Water

Chatterjee, Tanmay,Kim, Dong In,Cho, Eun Jin

, p. 7423 - 7430 (2018/07/29)

A transition-metal-free procedure for the synthesis of a highly valuable class of heteroaromatics, quinazolines, was developed by using easily available 2-aminobenzylamines and α,α,α-trihalotoluenes. The transformation proceeded smoothly in the presence of only sodium hydroxide and molecular oxygen in water at 100 °C, furnishing a variety of 2-aryl quinazolines. The crystallization process of the crude reaction mixture for the purification of the solid products circumvents huge solvent-consuming workup and column chromatographic techniques, which make the overall process more sustainable and economical.
