Check Digit Verification of cas no

The CAS Registry Mumber 1402665-60-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,6,6 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1402665-60:
(9*1)+(8*4)+(7*0)+(6*2)+(5*6)+(4*6)+(3*5)+(2*6)+(1*0)=134
134 % 10 = 4
So 1402665-60-4 is a valid CAS Registry Number.

Regioselective synthesis of pyrazole triflones based on triflyl alkyne cycloadditions

Kawai, Hiroyuki,Yuan, Zhe,Tokunaga, Etsuko,Shibata, Norio

supporting information, p. 5330 - 5333,4 (2020/09/02)

The regioselective synthesis of pyrazole triflones has been achieved by 1,3-dipolar cycloaddition of triflyl alkynes and hydrazonoyl chloride in the presence of Huenig's base. Pyrazolo[5,1-a]isoquinoline triflones were also regioselectively synthesized for the first time via tandem 1,3-dipolar cycloaddition/oxidative aromatization between triflyl alkynes and C,N-cyclic azomethine imines.
