Check Digit Verification of cas no

The CAS Registry Mumber 87671-67-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,7 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87671-67:
(7*8)+(6*7)+(5*6)+(4*7)+(3*1)+(2*6)+(1*7)=178
178 % 10 = 8
So 87671-67-8 is a valid CAS Registry Number.

One-pot synthesis of diarylamines from two aromatic amines via oxidative dearomatization-imino exchange-reductive aromatization

Zhang, Li,Wang, Weibin,Fan, Renhua

supporting information, p. 2018 - 2021 (2013/05/23)

A one-pot synthetic strategy for diarylamines using only aromatic amines as starting materials has been developed. This method involved a PhI(OAc) 2-induced oxidative dearomatization of N-sulfonyl protected para-substituted anilines, a Bi(OTf)3-catalyzed imino exchange reaction between N-sulfonyl cyclohexadienimines and aromatic amines, and a CF3COOH/Zn mediated reductive aromatization of the resulting N-aryl cyclohexadienimines.
