Check Digit Verification of cas no

The CAS Registry Mumber 156268-09-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,2,6 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156268-09:
(8*1)+(7*5)+(6*6)+(5*2)+(4*6)+(3*8)+(2*0)+(1*9)=146
146 % 10 = 6
So 156268-09-6 is a valid CAS Registry Number.

Synthesis of Aliphatic Azides by Photoinduced C(sp3)-H Azidation

Kamijo, Shin,Watanabe, Mizuki,Kamijo, Kaori,Tao, Keisuke,Murafuji, Toshihiro

, p. 115 - 121 (2016)

A photoinduced synthesis of aliphatic azides was achieved in a single step starting from the parent cyclic alkanes, as well as from tetrahydrofuran and pyrrolidine derivatives. The reaction proceeds via direct azidation of C(sp3)-H bonds in the presence of 4-benzoylpyridine under photoirradiation conditions utilizing tosyl azide as the azide source. The chemoselective C-H mono-azidation at room temperature and the formation of azide compounds in spite of their potential photolability are the key features of the present transformation.
