92868-69-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 92868-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,8,6 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 92868-69:
(7*9)+(6*2)+(5*8)+(4*6)+(3*8)+(2*6)+(1*9)=184
184 % 10 = 4
So 92868-69-4 is a valid CAS Registry Number.

Mass spectrometer as a probe in the synthesis of 2-substituted benzimidazoles

Ramana, Devalla V.,Kantharaj, Ethirajulu

, p. 2485 - 2496 (2007/10/02)

The pyrolysis of N,N'-diacyl-1,2-benzenediamines leads to the formation of 2-substituted benzimidazoles. This new synthetic approach towards the synthesis of 2-substituted benzimidazoles is developed based on the electron impact studies of N,N'-diacyl-1,2-benzenediamines under 70 eV conditions, in which important fragment ions corresponding to 2-substituted benzimidazoles are observed. The mechanisms and ion-structures, proposed in the mass spectral study, are supported by high-resolution, B/E and B2/E linked-scan spectra and Collision Activated Decomposition (CAD)-B/E linked-scan spectra.
