Check Digit Verification of cas no

The CAS Registry Mumber 259269-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,2,6 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 259269-58:
(8*2)+(7*5)+(6*9)+(5*2)+(4*6)+(3*9)+(2*5)+(1*8)=184
184 % 10 = 4
So 259269-58-4 is a valid CAS Registry Number.

Diels-Alder cycloadditions of N-arylpyrroles via aryne intermediates using diaryliodonium salts

Chen, Huangguan,Han, Jianwei,Wang, Limin

, p. 354 - 363 (2018)

With a strategy of the formation of benzynes by using diaryliodonium salts, a cycloaddition reaction of N-arylpyrroles with benzynes was reported. A wide range of bridge-ring amines with various substituents have been synthesized in moderate to excellent yields (35-96%). Furthermore, with a catalytic amount of TsOH·H2O, these amines can be converted into the corresponding N-phenylamine derivatives easily, which are potentially useful in photosensitive dyes.
