Check Digit Verification of cas no

The CAS Registry Mumber 108207-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,0 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108207-40:
(8*1)+(7*0)+(6*8)+(5*2)+(4*0)+(3*7)+(2*4)+(1*0)=95
95 % 10 = 5
So 108207-40-5 is a valid CAS Registry Number.

Conformational Preferences About Nsp2 - Csp2 Bond in N-Aryl- and N-(2'-Pyridyl)-camphorimides: A PMR Study

Vandana,Singh, R. M.,Verma, S. M.

, p. 724 - 728 (2007/10/02)

A number of N-aryl and N-(2'-pyridyl)-camphorimides (I-XII) have been prepared and their conformational analysis about the Nsp2 - Csp2 bond has been studied by PMR spectroscopy.The shielding parameters of β-methyl and o-substituent resonances demonstrate restricted rotation and non-planar conformations about the N - C bond and the preference of the sterically favoured conformation.Steric and electronic requirements of the sp2-hybridised nitrogen lone-pair are found to be effective in controlling the conformation about the N - C(pyridyl) bond. 13CNMR studies do not provide any valuable information about the different conformations.
