Check Digit Verification of cas no

The CAS Registry Mumber 91935-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,3 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91935-09:
(7*9)+(6*1)+(5*9)+(4*3)+(3*5)+(2*0)+(1*9)=150
150 % 10 = 0
So 91935-09-0 is a valid CAS Registry Number.

Synthesis of Halogenated Anilines by Treatment of N, N-Dialkylaniline N-Oxides with Thionyl Halides

Reed, Hayley,Paul, Tyler R.,Chain, William J.

, p. 11359 - 11368 (2018/08/06)

The special reactivity of N,N-dialkylaniline N-oxides allows practical and convenient access to electron-rich aryl halides. A complementary pair of reaction protocols allow for the selective para-bromination or ortho-chlorination of N,N-dialkylanilines in up to 69% isolated yield. The generation of a diverse array of halogenated anilines is made possible by a temporary oxidation level increase of N,N-dialkylanilines to the corresponding N,N-dialkylaniline N-oxides and the excision of the resultant weak N-O bond via treatment with thionyl bromide or thionyl chloride at low temperature.
