Check Digit Verification of cas no

The CAS Registry Mumber 6983-03-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,8 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6983-03:
(6*6)+(5*9)+(4*8)+(3*3)+(2*0)+(1*3)=125
125 % 10 = 5
So 6983-03-5 is a valid CAS Registry Number.

Structure determination of cyclopentane terpene derivatives by crossed NMR and MS techniques

Pianet, I.,Dolatkhani, M.,Cramail, H.,Deffieux, A.,Bourgeois, G.

, p. 1813 - 1818 (2007/10/03)

3 of the 4 stereoisomers of the 1-isopropenyl 2,3-dimethylcyclopentane, obtained from the cracking of 3,7-dimethylocta-1,6-diene, were purified and characterized.Dihedral angles, between the protons of the substituted carbons, have been determined by molecular modelling.Analysis of the NMR and mass spectra allowed us to access to the structure of the different isomers. - Keywords: cyclic monoterpene; structure determination; NMR; MS; molecular modelling
