The CAS Registry Mumber 86426-68-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,4,2 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 86426-68:
(7*8)+(6*6)+(5*4)+(4*2)+(3*6)+(2*6)+(1*8)=158
158 % 10 = 8

Synthesis and Properties of N-Phenyl Derivatives of 4,4'-Diaminobenzophenone

Evans, Neil A.

, p. 409 - 413 (2007/10/02)

Variations in the reaction conditions during the Ullmann condensation of 4,4'-diaminobenzophenone with iodobenzene and the Goldberg diphenylamine synthesis with 4,4'-dibromobenzophenone and acetanilide or 4,4'-bis(acetamido)benzophenone and iodobenzene yielded the five possible partially and completely N-Phenylated 4,4'-diaminobenzophenones.By choice of starting materials, 4,4'-bis(phenylamino)benzophenone could be obtained in satisfactory yield.The infrared, ultraviolet, 1H and 13C nuclear magnetic resonance and mass spectra of the benzophenones are reported.
