Check Digit Verification of cas no

The CAS Registry Mumber 1160967-80-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,0,9,6 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1160967-80:
(9*1)+(8*1)+(7*6)+(6*0)+(5*9)+(4*6)+(3*7)+(2*8)+(1*0)=165
165 % 10 = 5
So 1160967-80-5 is a valid CAS Registry Number.

Palladium-Catalyzed Carbonylative Synthesis of 2-(Trifluoromethyl)quinazolin-4(3H)-ones from Trifluoroacetimidoyl Chlorides and Nitro Compounds

Wang, Le-Cheng,Zhang, Yu,Chen, Zhengkai,Wu, Xiao-Feng

, p. 1417 - 1426 (2021)

A procedure on palladium-catalyzed carbonylative reaction of trifluoroacetimidoyl chlorides and nitro compounds for the construction of pharmaceutically valuable 2-(trifluoromethyl)quinazolin-4(3H)-ones has been achieved. In this transformation, Mo(CO)6 has been used both as a convenient CO source and a reducing reagent. This newly developed protocol is compatible with various nitro compounds and can be readily scaled up to 1 mmol scale. (Figure presented.).

FeCl3-Mediated Synthesis of 2-(Trifluoromethyl)quinazolin-4(3 H)-ones from Isatins and Trifluoroacetimidoyl Chlorides

Wang, Le-Cheng,Du, Shiying,Chen, Zhengkai,Wu, Xiao-Feng

supporting information, p. 5567 - 5571 (2020/07/14)

An FeCl3-mediated cascade coupling/decarbonylative annulation reaction for the efficient construction of 2-(trifluoromethyl)quinazolin-4(3H)-ones has been developed. This transformation employs readily available isatins and trifluoroacetimidoyl chlorides as the starting materials, providing a facile and practical route to diverse biologically relevant quinazolin-4(3H)-one derivatives. A plausible reaction pathway has been proposed based on the mechanistic observations.
