Check Digit Verification of cas no

The CAS Registry Mumber 1297518-94-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,7,5,1 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1297518-94:
(9*1)+(8*2)+(7*9)+(6*7)+(5*5)+(4*1)+(3*8)+(2*9)+(1*4)=205
205 % 10 = 5
So 1297518-94-5 is a valid CAS Registry Number.

1H, 13C NMR, FT-IR, ESI MS and PM5 studies of a new 3,6,9-trioxadecylamide of monensin A and its complexes with Li+, Na+ and K+ cations

?owicki, Daniel,Huczyński, Adam,Brzezinski, Bogumil,Bartl, Franz

, p. 121 - 131 (2011)

A new 3,6,9-trioxadecylamide of monensin A (M-AM4) has been synthesised and its ability to form complexes with Li+, Na+ and K + cations has been studied by ESI mass spectrometry, 1H and 13C NMR, FT-IR spectroscopy and PM5 semiempirical method. The ESI MS data indicate that M-AM4 forms complexes with Li+, Na+ and K+ of exclusively 1:1 stoichiometry which are stable up to cv = 70 V. The formation of the M-AM4-Na+ is strongly favoured. Above cv = 70 the fragmentation process is observed. The spectroscopic studies show that the structures of the M-AM4 and its complexes with the cations of 1:1 stoichiometry are stabilized by intramolecular hydrogen bonds in which the OH groups are always involved. The CO amide group is engaged in the complexation process of each cation. The M-AM4-K+ complex can also assume a structure in which the CO amide group does not participate in the complexation but the complexes of such structure do not dominate.
