Check Digit Verification of cas no
The CAS Registry Mumber 2969-67-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,6 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2969-67:
(6*2)+(5*9)+(4*6)+(3*9)+(2*6)+(1*7)=127
127 % 10 = 7
So 2969-67-7 is a valid CAS Registry Number.

A General Synthesis of Substituted Fluorenones and Azafluorenones

Twenty-one variously substituted fluorenones and azafluorenones have been synthesized via photochemical Pschorr cyclizations of 2-diazoniodiaryl ketones as the key ring-forming step.Direct, (bipy)3RuII-, or (bipy)3RuII/CuII-photosensitized conditions were used, depending on the system to be cyclized.Where selectivities were possible in the ring closure, the isomer ratios obtained were in accord with an aryl radical as the reactive intermediate.The precursor aminodiaryl ketones were obtained from the sequence ortho lithiation of an arylpivalamide, reaction withan aryl aldehyde to give a 2-pivalamidodiarylcarbinol, oxidation to give a 2-pivalamidodiaryl ketone, and hydrolysis to give the 2-aminodiaryl ketone.
