Check Digit Verification of cas no

The CAS Registry Mumber 6189-11-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,8 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6189-11:
(6*6)+(5*1)+(4*8)+(3*9)+(2*1)+(1*1)=103
103 % 10 = 3
So 6189-11-3 is a valid CAS Registry Number.

Fluoroalkyl-Substituted Diazomethanes and Their Application in a General Synthesis of Pyrazoles and Pyrazolines

Mertens, Lucas,Hock, Katharina J.,Koenigs, Rene M.

, p. 9542 - 9545 (2016)

A novel continuous-flow approach for the synthesis of fluoroalkyl-substituted diazomethanes has been developed. Utilizing a cheap, self-made microreactor fluoroalkyl-substituted amines were transformed into the corresponding diazomethanes using tert-butyl nitrite and acetic acid as catalyst. These diazomethanes were employed in [2+3] cycloaddition reactions with olefins and alkynes, yielding valuable pyrazolines and pyrazoles in good to excellent yields.
