Check Digit Verification of cas no

The CAS Registry Mumber 945041-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,0,4 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 945041-53:
(8*9)+(7*4)+(6*5)+(5*0)+(4*4)+(3*1)+(2*5)+(1*3)=162
162 % 10 = 2
So 945041-53-2 is a valid CAS Registry Number.

Model reactions for preparing poly(imino-tetrafluoro-1,4-phenylene)

Koppang, Rolf

, p. 1505 - 1509 (2008/09/16)

2,3,4,5,6-Pentafluoroformanilide was prepared giving, in addition, two new compounds 4,5,6,7-tetrafluoro-1-pentafluorophenyl-benzimidazole and 2,3,4,5-tetrafluoro-6-[(pentafluorophenyl)amino]formanilide. Sodium 2,3,4,5,6-pentafluoro-formanilide was reacted with hexafluorobenzene in a molar ratio of 1:4 to give oligomers of α-pentafluorophenyl-ω-fluoro-poly(imino-tetrafluoro-1,4-phenylene). Some of the oligomers were isolated. The results indicate that poly(imino-tetrafluoro-1,4-phenylene) could be formed. Model reaction on hexafluorobenzene with sodium acetanilide, molar ratio 1:2, gave a low yield of N,N′-diacetyl-diphenyl-tetrafluoro-1,4-phenylenediamine.
