Check Digit Verification of cas no
The CAS Registry Mumber 4433-88-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4433-88:
(6*4)+(5*4)+(4*3)+(3*3)+(2*8)+(1*8)=89
89 % 10 = 9
So 4433-88-9 is a valid CAS Registry Number.

Sterically Hindered Free Radicals. Part 20. EPR and ENDOR Spectroscopy of α-Carbonyl Radicals
Kubiak, Bernd,Lehnig, Manfred,Neumann, Wilhelm P.,Pentling, Ursula,Zarkadis, Antonios K.
, p. 1443 - 1447 (2007/10/02)
The hyperfine coupling constants and g values of 11 α-carbonyl radicals CR1R2(CRO) (1) and CR3(CN)(CRO) (2) (R = H, Me, Ph, α-Naph; R1, R2, R3 = H, CO2Et, Ph, 2,4-Me2Ph, Mes) have been determined by EPR and, partially, ENDOR spectroscopy.The g values lie between 2.0025 and 2.0051.Except for CH(CO2Et)(CMeO)-radical, the g values are smaller than expected because of the steric hindrance of the substituents R1, R2 and R3.The CRO group is twisted out of the nodal plane of the radical which diminishes the delocalisation of the unpaired electron over the carboxyl group.The proton splittings in the α-aryl substituents differ significantly from those found in CH2Ph-radical because of distortions.Proton splittings in benzoyl groups have been observed for the first time.
