Check Digit Verification of cas no

The CAS Registry Mumber 1430334-18-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,0,3,3 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1430334-18:
(9*1)+(8*4)+(7*3)+(6*0)+(5*3)+(4*3)+(3*4)+(2*1)+(1*8)=111
111 % 10 = 1
So 1430334-18-1 is a valid CAS Registry Number.

Regioselective synthesis of imidazo[1,2-a][1,3,5]triazines and 3,4-dihydroimidazo[1,2-a][1,3,5]triazines from [1,3,5]triazin-2,4-diamines

Dao, Pascal,Garbay, Christiane,Chen, Huixiong

, p. 3867 - 3871 (2013/07/05)

An efficient and practical procedure was developed to prepare novel imidazo[1,2-a][1,3,5]triazines and 3,4-dihydroimidazo[1,2-a][1,3,5]triazines with a good regioselectivity and high yields, starting from dicyandiamide and the corresponding arylamines. Mechanistic studies for the subsequent cyclocondensation with chloroacetaldehyde support a pathway, which begins with the displacement of the chloro atom activated by an adjacent CO group, followed by cyclization and dehydration.
