Check Digit Verification of cas no

The CAS Registry Mumber 178970-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,9,7 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 178970-77:
(8*1)+(7*7)+(6*8)+(5*9)+(4*7)+(3*0)+(2*7)+(1*7)=199
199 % 10 = 9
So 178970-77-9 is a valid CAS Registry Number.

Reactions of Ethyl 5,6,7,8-Tetrafluoro-4-oxo-4H-1-benzopyran-2-carboxylate with N-(2-Aminoethyl)ethylenediamine and N-(2-Hydroxyethyl)ethylenediamine

Saloutin, V. I.,Bazyl', I. T.,Skryabina, Z. E.,Kodess, M. I.,Chupakhin, O. N.

, p. 1293 - 1297 (2007/10/03)

Ethyl 5,6,7,8-tetrafluoro-4-oxo-4H-1-benzopyran-2-carboxylate reacts with N-(2-aminoethyl)ethylenediamine and N-(2-hydroxyethyl)ethylenediamine, forming derivatives of pyrazinopyrazine and 4-(2-hydroxyethyl)piperazin-2-one, respectively.The structure of the products was proved by IR and 1H and 19F NMR spectroscopy and chemical transformations.A stable salt of pyrazinopyrazine with trifluoroacetic acid was isolated.
