Check Digit Verification of cas no

The CAS Registry Mumber 82880-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,8 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82880-44:
(7*8)+(6*2)+(5*8)+(4*8)+(3*0)+(2*4)+(1*4)=152
152 % 10 = 2
So 82880-44-2 is a valid CAS Registry Number.

Facile Cu(I)-catalyzed oxidative coupling of anilines to azo compounds and hydrazines with diaziridinone under mild conditions

Zhu, Yingguang,Shi, Yian

supporting information, p. 1942 - 1945 (2013/06/04)

A mild and highly efficient Cu(I)-catalyzed oxidative coupling of anilines is described. Various primary and secondary anilines can be efficiently coupled under mild conditions to the corresponding azo compounds and hydrazines in high yields. This method provides a direct and practical access to these compounds and is also amenable to gram scale with no special precautions to exclude air or moisture.
