148004-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148004-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,0,0 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 148004-80:
(8*1)+(7*4)+(6*8)+(5*0)+(4*0)+(3*4)+(2*8)+(1*0)=112
112 % 10 = 2
So 148004-80-2 is a valid CAS Registry Number.

Nucleophilic displacement of fluorine from fluorodiarylacetylenes by alkoxide and phenoxide
Paventi,Hay
, p. 999 - 1002 (1993)
Difluoroarylacetylenes synthesized in dimethylformamide in the presence of potassium tert-butoxide from fluorobenzyl-1H(or 2H)benzotriazoles and N-fluorophenylmethyleneanilines, undergo facile displacement of fluorine by tert-butoxide and phenoxide.
