88919-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88919-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,9,1 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 88919-89:
(7*8)+(6*8)+(5*9)+(4*1)+(3*9)+(2*8)+(1*9)=205
205 % 10 = 5
So 88919-89-5 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 (2007/10/02)
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.
