80576-42-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80576-42-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,7 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80576-42:
(7*8)+(6*0)+(5*5)+(4*7)+(3*6)+(2*4)+(1*2)=137
137 % 10 = 7
So 80576-42-7 is a valid CAS Registry Number.

Aryne and SNAr Reactions of Polyhalogenobenzenes. 6. Synthesis of Benzofurans
Bachelet, Jean-Pierre,Caubere, Paul
, p. 234 - 238 (1982)
The scope and limitations of the one-pot synthesis of benzofurans by aryne condensations of the cyclic ketone enolates with dihalogenobenzenes in the presence of the complex base NaNH2-t-BuONa were studied.It is shown that this method is of interest for t
