94742-31-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94742-31-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,7,4 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 94742-31:
(7*9)+(6*4)+(5*7)+(4*4)+(3*2)+(2*3)+(1*1)=151
151 % 10 = 1
So 94742-31-1 is a valid CAS Registry Number.

SYNTHESIS AND SPECTROSCOPIC CHARACTERISTICS OF 2,3'-BIINDOLYLS AND 2,2'-INDOLYLPYRROLES
Bocchi, Vittorio,Palla, Gerardo
, p. 3251 - 3256 (1984)
A general and selective method has been achieved to synthesize 2,3'-biindolyls and 2,2'-indolylpyrroles through an acid catalyzed reaction of 3-bromoindoles with indoles or pyrroles.I.R., (1)H-NMR, (13)C-NMR and MS data of the dimers are also reported.
