Check Digit Verification of cas no

The CAS Registry Mumber 4015-30-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,1 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4015-30:
(6*4)+(5*0)+(4*1)+(3*5)+(2*3)+(1*0)=49
49 % 10 = 9
So 4015-30-9 is a valid CAS Registry Number.

Silver-Catalyzed Isocyanide Insertion into N?H Bond of Ammonia: [5+1] Annulation to Quinazoline Derivatives

Zhang, Lingjuan,Li, Juanjuan,Hu, Zhongyan,Dong, Jinhuan,Zhang, Xian-Ming,Xu, Xianxiu

, p. 1938 - 1942 (2018/04/02)

A silver-catalyzed [5+1] annulation of o-acylaryl isocyanides with ammonium acetate and hydroxlamine was developed for the efficient and practical synthesis of quinazolines and quinazoline 3-oxides in good to excellent yields, respectively. The domino process involved an unprecedented isocyanide insertion into the N?H bond of ammonia or hydroxylamine and followed by condensation reaction at ambient conditions. (Figure presented.).
