Check Digit Verification of cas no

The CAS Registry Mumber 183007-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,0,0 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 183007-01:
(8*1)+(7*8)+(6*3)+(5*0)+(4*0)+(3*7)+(2*0)+(1*1)=104
104 % 10 = 4
So 183007-01-4 is a valid CAS Registry Number.

EPR investigations of β-deuteriated 5,5"-dimethyl-2,2':5',2"-terthiophenes

Engelmann, Guennar,Stoesser, Reinhard,Kossmehl, Gerhard,Jugelt, Werner,Welzel, Hans-Peter

, p. 2015 - 2020 (2007/10/03)

The unambiguous assignment of the β-hyperfine coupling constants of the radical cations of 5,5"-dimethyl-2,2':5',2"-terthiophene (11) has been achieved by EPR spectroscopic investigations of the deuteriated compounds 12, 13, and 14.The syntheses of these substances were achieved by cross-coupling following the Negishi and Kumada reaction starting from deuteriated derivatives of chloromethylated thiophene derivatives.The generation of the radical cations was carried out by electrochemical oxidation at a constant potential in the EPR spectrometr.In the presence of acidic compounds a D-H exchange at the β-positions of oligothiophenes was observed.The experimentally determined spin density distribution was rationalized by means of semiempirical quantum mechanical calculations (RHF-INDO-SP).Theoretical and experimental assignments are in good agreement.
