Check Digit Verification of cas no
The CAS Registry Mumber 117847-23-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,4 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117847-23:
(8*1)+(7*1)+(6*7)+(5*8)+(4*4)+(3*7)+(2*2)+(1*3)=141
141 % 10 = 1
So 117847-23-1 is a valid CAS Registry Number.

Electrophilic nitration of triphenylamines as a route to high oxidation potential electrocatalysts. Polynitration, nitrodebromination, and bromine dance
Wu, Xin,Dube, Mufaro A.,Fry, Albert J.
, p. 7667 - 7669 (2007/10/03)
The nitration of triphenylamine derivatives is facile, readily leading to an introduction of up to three nitro groups at room temperature. The nitration of 4,4′,4″-tribromotriphenylamine results in nitrodebromination on one or more rings and bromination a
