Check Digit Verification of cas no

The CAS Registry Mumber 1373169-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,1,6 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1373169-81:
(9*1)+(8*3)+(7*7)+(6*3)+(5*1)+(4*6)+(3*9)+(2*8)+(1*1)=173
173 % 10 = 3
So 1373169-81-3 is a valid CAS Registry Number.

Metal-Free Oxidative Annulation/Cyclization of 1,6-Enynes for the Synthesis of 4-Carbonylquinolines

Xia, Xiao-Feng,He, Wei,Wang, Dawei

supporting information, p. 2959 - 2964 (2019/04/30)

Herein we report on the development of a metal-free oxidative annulation reaction of 1,6-enynes, leading to 4-carbonylquinolines by using dioxygen as a green sustainable oxidant. Key advances include the use of readily available tert-butyl nitrite (TBN) to promote radical annulation of 1,6-enynes and easy-to-handle reaction conditions. Preliminary mechanistic studies including radical capture reactions and isotope labelling experiments are also conducted. (Figure presented.).

Copper-catalyzed oxidative cyclization of enynes for the synthesis of 4-carbonyl-quinolines with O2

Xia, Xiao-Feng,Zhang, Lu-Lu,Song, Xian-Rong,Liu, Xue-Yuan,Liang, Yong-Min

, p. 2480 - 2483 (2012/07/13)

A novel copper-catalyzed oxidative cyclization of enynes and in situ formed enynes leading to 4-carbonyl-quinolines by using dioxygen as an oxygen source has been developed.
