Check Digit Verification of cas no

The CAS Registry Mumber 180284-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,2,8 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180284-25:
(8*1)+(7*8)+(6*0)+(5*2)+(4*8)+(3*4)+(2*2)+(1*5)=127
127 % 10 = 7
So 180284-25-7 is a valid CAS Registry Number.

A new route to aminodiazines via metalation reaction. Synthesis of an aza analogue of Nevirapine: Diazines XV

Plé, Nelly,Turck, Alain,Couture, Karine,Quéguiner, Guy

, p. 838 - 842 (1996)

A new route to aminodiazines is reported, the ortho-directed lithiation of diazines is used, followed by reaction with tosyl azide as an electrophile. The reduction of the azido or tetrazolo compounds obtained was achieved and led to the expected amines. This methodology has allowed the synthesis of new aminodiazines and an improvement in the yield of various aminodiazines previously described. This reaction was used for the preparation of an aza analogue of Nevirapine.
