80663-28-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80663-28-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,6 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80663-28:
(7*8)+(6*0)+(5*6)+(4*6)+(3*3)+(2*2)+(1*8)=131
131 % 10 = 1
So 80663-28-1 is a valid CAS Registry Number.

Low-valent niobium-mediated synthesis of indenes: Intramolecular coupling reaction of CF3 group with alkene C-H bond
Fuchibe, Kohei,Mitomi, Ken,Akiyama, Takahiko
, p. 24 - 25 (2007/10/03)
CF3 group of o-alkenyl-α,α,α-trifluorotoluenes underwent intramolecular coupling reaction with the alkene C-H bond under NbCl5/LiAlH4 system. Substituted indenes were obtained in good yields. Copyright
