Check Digit Verification of cas no

The CAS Registry Mumber 5014-43-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,1 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5014-43:
(6*5)+(5*0)+(4*1)+(3*4)+(2*4)+(1*3)=57
57 % 10 = 7
So 5014-43-7 is a valid CAS Registry Number.

The Structure of Amidyl Radicals. Evidence for the ?-Electronic Ground State and for Twist about the Acyl-Nitrogen Bond by Electron Paramagnetic Resonance Spectroscopy

Sutcliffe, R.,Griller, D.,Lessard, J.,Ingold, K. U.

, p. 624 - 628 (2007/10/02)

The EPR spectroscopic parameters for a number of acyclic N-alkylcarboxamidyls, RC(O)R', have been measured over a wide range of temperatures.The results can only be interpreted in terms of ?-electronic configuration in which the unpaired electron resides mainly in an N 2p orbital perpendicular to the RNC plane.Measurements of the 13C hyperfine splittings (hfs) for some RC(O)(13)CH3 demonstrate that the O and 13C atoms lie in or near the RNC plane except when R ist tert-butyl, in which case steric forces twist these atoms out of this plane by 20 deg or more.There is less conjugative delocalization of the unpaired electron from N to O in the Me3CC(O)R' radicals because they are twisted and hence these radicals have a larger N hfs and a smaller g value than amidyls which have R = primary or secondary alkyl.The first cyclic amidyl, 5,5-dimethyl-2-oxopyrrolidin-1-yl, has been detected.This radical has a smaller N hfs (11.2 G) and a higher g value (2.0063) than the acyclic radicals.
