Check Digit Verification of cas no

The CAS Registry Mumber 1436413-21-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,6,4,1 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1436413-21:
(9*1)+(8*4)+(7*3)+(6*6)+(5*4)+(4*1)+(3*3)+(2*2)+(1*1)=136
136 % 10 = 6
So 1436413-21-6 is a valid CAS Registry Number.

Preparation of 2-arylquinolines from β-arylpropionitriles with aryllithiums and NIS through iminyl radical-mediated cyclization

Naruto, Hiroki,Togo, Hideo

, p. 5760 - 5770 (2019/06/18)

Treatment of β-arylpropionitriles with aryllithiums, followed by the reaction with water and then with NIS under irradiation with a tungsten lamp gave 2-arylquinolines in good to moderate yields. The present reaction proceeds through the formation of N-iodoimines from imines with NIS, the generation of imino-nitrogen-centered radicals, and their cyclization onto the aromatic rings of the imines to form 2-aryl-3,4-dihydroquinolines. Finally, the oxidation of 2-aryl-3,4-dihydroquinolines with NIS proceeds smoothly to generate 2-arylquinolines.
