Check Digit Verification of cas no
The CAS Registry Mumber 502845-02-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,8,4 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 502845-02:
(8*5)+(7*0)+(6*2)+(5*8)+(4*4)+(3*5)+(2*0)+(1*2)=125
125 % 10 = 5
So 502845-02-5 is a valid CAS Registry Number.

Formation of indole nucleus via intramolecular cyclization of aminophenylpropenyltriphenylphosphonium salts with one-carbon degradation
Taira, Shin'Ichi,Danjo, Hiroshi,Imamoto, Tsuneo
, p. 8893 - 8896 (2007/10/03)
Treatment of 3-(2-aminophenyl)-2-propenyltriphenylphosphonium bromide with acid anhydride and tertiary amine affords 1,3-diacylindoles in yields ranging from 22 to 64%. A plausible mechanism of this new cyclization reaction is described.
