1417792-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1417792-92-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,7,9 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1417792-92:
(9*1)+(8*4)+(7*1)+(6*7)+(5*7)+(4*9)+(3*2)+(2*9)+(1*2)=187
187 % 10 = 7
So 1417792-92-7 is a valid CAS Registry Number.

Repetitive synthetic method for o, o, p-oligophenylenes using C-H arylation
Manabe, Kei,Kimura, Takeshi
, p. 374 - 377 (2013/03/13)
A synthetic method for the preparation of o,o,p-oligophenylenes has been developed. It involves Miura's C-H arylation of 2-biphenols with aryl nonaflates as the key step. Oligophenylenes with defined lengths are successfully synthesized using this method.
