Check Digit Verification of cas no
The CAS Registry Mumber 5121-76-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5121-76:
(6*5)+(5*1)+(4*2)+(3*1)+(2*7)+(1*6)=66
66 % 10 = 6
So 5121-76-6 is a valid CAS Registry Number.

Formation of perfluorinated polyphenylenes by multiple pentafluorophenylation using C6F5Si(CH3) 3
Nishida, Masakazu,Hayakawa, Yoshio,Ono, Taizo
experimental part, p. 1314 - 1321 (2011/02/22)
Pentafluorophenylation of perfluoroarenes with C6F 5Si(CH3)3 was investigated by using NMR and MALDI-TOF-MS techniques. Successive multiple pentafluorophenylation easily occurred not only on the para-position but also on the ortho-positions to provide perfluorinated p-phenylene and m-phenylene compounds. The perfluoroarenes having electron-withdrawing substituents provided oligo- to poly-(phenylene)s depending on the added amounts of C6F 5Si(CH3)3, while the perfluoroarenes having electron-donor substituents gave H(C6F4)nF polymers produced from C6F5H, which was the decomposed product of C6F5Si(CH3)3.
