Check Digit Verification of cas no

The CAS Registry Mumber 131302-01-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,0 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131302-01:
(8*1)+(7*3)+(6*1)+(5*3)+(4*0)+(3*2)+(2*0)+(1*1)=57
57 % 10 = 7
So 131302-01-7 is a valid CAS Registry Number.

A series of assembled heterocyclic bases containing picolines and X-azolopyridines was synthesized, thus widening the outline of available compounds for a comparison of their chemical , physical and spectroscopic properties.In particular, the competition of three different sites toward quaternizing agents has been explored and individual behaviours have been clarified by 1H nmr spectroscopy.Styryl dyes have been prepared and characterized.The effect of cationic and anionic surfactants on deaggregating one unsymmetrical cyanine has been successfully tested.
