Check Digit Verification of cas no
The CAS Registry Mumber 74396-74-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,9 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74396-74:
(7*7)+(6*4)+(5*3)+(4*9)+(3*6)+(2*7)+(1*4)=160
160 % 10 = 0
So 74396-74-0 is a valid CAS Registry Number.

A novel strategy to the synthesis of 4-anilinoquinazoline derivatives
Wang, Zheng,Wang, Cuiling,Sun, Yanni,Zhang, Ning,Liu, Zhulan,Liu, Jianli
, p. 906 - 913 (2014/01/23)
A novel approach to prepare 4-anilinoquinazoline derivatives based on the transformation of indoline-2,3-dione to formamidine was developed. The processes with this approach are simple, efficient, and environmentally friendly. The efficiency of this approach was evaluated by synthesizing 17 4-anilinoquinazolines and comparing the obtained yields with those achievable through conventional synthetic methods. It was the first time that compounds 8d, 8e, 8h, and 13b-f were synthesized. The characteristics of the IR and the UV spectra of these compounds and the effects of their substituents on the spectra were observed.
Synthesis of isatin 3-oximes from 2-nitroacetanilides
Kearney,Harris,Jackson,Joule
, p. 769 - 772 (2007/10/02)
2-Nitroacetanilides, prepared by alkaline hydrolysis of 1-arylamino-1-methylthio-2-nitroethenes, are converted into isatin (1H-indole-2,3-dione) 3-oximes by treatment with concentrated sulfuric acid or trifluoromethanesulfonic acid at room temperature.
