Check Digit Verification of cas no

The CAS Registry Mumber 113439-96-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,3 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 113439-96:
(8*1)+(7*1)+(6*3)+(5*4)+(4*3)+(3*9)+(2*9)+(1*6)=116
116 % 10 = 6
So 113439-96-6 is a valid CAS Registry Number.

Metal-Free Synthesis of N-Aryl-Substituted Azacycles from Cyclic Ethers Using POCl3

La, Minh Thanh,Kang, Soosung,Kim, Hee-Kwon

, p. 6689 - 6696 (2019)

A facile method for the synthesis of N-aryl-substituted azacycles from arylamines and cyclic ethers has been developed. In this study, arylamines were treated with cyclic ethers in the presence of POCl3 and DBU to provide five- A nd six-membered azacycles. Using this method, various azacycloalkanes, isoindolines, and tetrahydroisoquinolines were prepared in high yields. This synthetic method offers an efficient approach to the production of azacycles from cyclic ethers.
