Check Digit Verification of cas no

The CAS Registry Mumber 634901-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,9,0 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 634901-87:
(8*6)+(7*3)+(6*4)+(5*9)+(4*0)+(3*1)+(2*8)+(1*7)=164
164 % 10 = 4
So 634901-87-4 is a valid CAS Registry Number.

Fluorinated benzimidazo[1,2-a]quinolones

Lipunova,Nosova,Vasil'eva,Charushin

, p. 457 - 460 (2003)

The reactions of 2-cyanomethylbenzimidazole with polyfluorobenzoyl chlorides afforded 2-(1,3-dihydrobenzimidazol-2-ylidene)-3-oxo-3- polyfluorophenylpropionitriles. Refluxing of the latter compounds hi acetonitrile in the presence of DBU or in dimethylformamide in the presence of amines gave rise to fluorine-containing derivatives of benzimidazo[1,2-a] quinolone.
