Check Digit Verification of cas no

The CAS Registry Mumber 38131-83-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,1,3 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38131-83:
(7*3)+(6*8)+(5*1)+(4*3)+(3*1)+(2*8)+(1*3)=108
108 % 10 = 8
So 38131-83-8 is a valid CAS Registry Number.

Transition-Metal-Free Dehydrogenative N–N Coupling of Secondary Amines with KI/KIO4

Yin, Dehang,Jin, Jian

, p. 5646 - 5649 (2019)

A transition-metal-free method for the dehydrogenative N–N coupling of secondary amines has been accomplished. This oxidative KI/KIO4 protocol is mild and operationally simple. A diverse range of diphenylamines, carbazoles, and N-alkylanilines readily undergo N–N homo-coupling effectively. Notably, the N–N cross-coupling of two different arylamines is also demonstrated, which provides a straightforward approach to the complex N–N structures.
