Check Digit Verification of cas no

The CAS Registry Mumber 155579-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,5,7 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 155579-17:
(8*1)+(7*5)+(6*5)+(5*5)+(4*7)+(3*9)+(2*1)+(1*7)=162
162 % 10 = 2
So 155579-17-2 is a valid CAS Registry Number.

New application of heterocyclic diazonium salts. Synthesis of pyrazolo[3,4-d][1,2,3]triazin-4-ones and imidazo[4,5-d][1,2,3]triazin-4-ones

Colomer, Juan Pablo,Moyano, Elizabeth Laura

scheme or table, p. 1561 - 1565 (2011/05/05)

The pyrazolo[3,4-d][1,2,3]triazin-4-ones 3 and imidazo[4,5-d][1,2,3] triazin-4-ones 4 are analogs structurally related to purines that have showed a wide and significant variety of biological activity. These compounds were synthesized by one-pot diazotization of 5-amino-1H-pyrazole-4-carbonitriles 1 and 5-amino-1H-imidazole-4-carbonitriles 2, respectively.

A Facile Synthesis of 5-Amino-4-cyano-1-arylimidazoles and 5-Amino-1-aryl-4-(cyanoformimidoyl)-1H-imidazoles from N-Aryl-N'-formamidines

Alves, M. Jose,Booth, Brian L,Al-Duaij, Omar Kh.,Eastwood, Paul,Nezhat, Lida,et al.

, p. 2701 - 2719 (2007/10/02)

Starting from readily available ethyl (Z)-N-(2-amino-1,2-dicyanovinyl)formimidate, N-aryl-N'-formamidines (2) can be prepared in good yields by reaction with aromatic amines at room temperature in the presence of an acid catalyst
