Check Digit Verification of cas no
The CAS Registry Mumber 1301190-16-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,1,1,9 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1301190-16:
(9*1)+(8*3)+(7*0)+(6*1)+(5*1)+(4*9)+(3*0)+(2*1)+(1*6)=88
88 % 10 = 8
So 1301190-16-8 is a valid CAS Registry Number.

Structure of reaction products of 3-cyanochromones with ethylenediamine
Sosnovskikh, V. Ya.,Moshkin,El'Tsov
, p. 2151 - 2154 (2010)
A reaction of 3-cyanochromones with ethylenediamine in ethanol afforded N,N′-ethyl-ene-bis(2-amino-3-iminomethylchromones), which depending on the time of reflux in acetic acid give 2-amino-3-formylchromones or products of their dimerization, 2-(chromon-3-yl)-5H-chromeno[2,3-d]pyrimidin-5-ones.
