Check Digit Verification of cas no

The CAS Registry Mumber 84907-66-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,0 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 84907-66:
(7*8)+(6*4)+(5*9)+(4*0)+(3*7)+(2*6)+(1*6)=164
164 % 10 = 4
So 84907-66-4 is a valid CAS Registry Number.

Fast and Efficient Continuous Flow Method for the Synthesis of Ynones and Pyrazoles

Kandasamy, Mohanraj,Ganesan, Balaji,Hung, Min-Yuan,Lin, Wei-Yu

, p. 3183 - 3189 (2019)

In this study, we developed a convenient and efficient two-step method for the synthesis of ynones in a flow reactor, through the generation of lithium acetylide and its subsequent reactions with acid chlorides. Using this approach, we obtained the ynones in moderate to good yields at room temperature. Moreover, we transformed the ynones into pyrazole derivatives through coupling with hydrazines. This transition metal-free process, mild reaction conditions, and broad functional group tolerance are all attractive features in comparison with conventional bench-top methods.

Yamaguchi, Masahiko,Waseda, Toshie,Hirao, Ichiro

, p. 35 - 36 (2007/10/02)

Alkynyl ketones are synthesized in high yields by the reaction of alkynyl boranes and amides under a mild reaction condition.
