Check Digit Verification of cas no

The CAS Registry Mumber 195968-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,9,6 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 195968-92:
(8*1)+(7*9)+(6*5)+(5*9)+(4*6)+(3*8)+(2*9)+(1*2)=214
214 % 10 = 4
So 195968-92-4 is a valid CAS Registry Number.

Catalytic Selective Oxidative Coupling of Secondary N-Alkylanilines: An Approach to Azoxyarene

Azoxyarenes are among important scaffolds in organic molecules. Direct oxidative coupling of primary anilines provides a concise fashion to construct them. However, whether these scaffolds can be prepared from secondary N-alkylanilines is not well explored. Here, we present a catalytic selective oxidative coupling of secondary N-alkylaniline to afford azoxyarene with tungsten catalyst under mild conditions. In addition, azoxy can be viewed as a bioisostere of alkene and amide. Several "azoxyarene analogues" of the corresponding bioactive alkenes and amides showed comparable promising anticancer activities.
