Check Digit Verification of cas no

The CAS Registry Mumber 25706-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,0 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25706-78:
(7*2)+(6*5)+(5*7)+(4*0)+(3*6)+(2*7)+(1*8)=119
119 % 10 = 9
So 25706-78-9 is a valid CAS Registry Number.

A three-dimensional hydrogen-bonded framework in 2-amino-6-(N- methylanilino)pyrimidin-4(3H)-one and a ribbon of fused hydrogen-bonded rings in 2-amino-6-(N-methylanilino)-5-nitropyrimidin-4(3H)-one

, p. o697-o700 (2008/09/19)

The mol-ecular dimensions of both 2-amino-6-(N-methyl-anilino)pyrimidin- 4(3H)-one, C11H12N4O, (I), and 2-amino-6-(N-methyl-anilino)-5-nitro-pyrimidin- 4(3H)-one, C11H11N5O3, (II), are consistent with considerable polarization of the mol-ecular-electronic structures. The mol-ecules of (I) are linked into a three-dimensional framework by a combination of one N - H...N hydrogen bond, two independent N - H...O hydrogen bonds and one C - H...π(arene) hydrogen bond. The mol-ecules of (II) are linked into ribbons containing three types of edge-fused ring by the combination of two independent three-centre N - H...(O)2 hydrogen bonds.
