53165-17-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53165-17-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,6 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53165-17:
(7*5)+(6*3)+(5*1)+(4*6)+(3*5)+(2*1)+(1*7)=106
106 % 10 = 6
So 53165-17-6 is a valid CAS Registry Number.

A Convenient Formal [4+2] Heterocylization Route to Bis(triflyl)tetrahydroquinolines

Lázaro-Milla, Carlos,Almendros, Pedro

, p. 13534 - 13538 (2021/08/13)

We report the sustainable and efficient synthesis of a new type of quinoline derivatives bearing one or two SO2CF3 groups. The protocol is metal-, catalyst- and irradiation-free, involves the use of readily available and stable precursors, and avoids the formation of side products. Also, the mild conditions of the process allow the tolerance of a wide range of functional groups.
