Check Digit Verification of cas no

The CAS Registry Mumber 868528-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,8,5,2 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 868528-72:
(8*8)+(7*6)+(6*8)+(5*5)+(4*2)+(3*8)+(2*7)+(1*2)=227
227 % 10 = 7
So 868528-72-7 is a valid CAS Registry Number.

Suzuki reactions with stable organic radicals - Synthesis of biphenyls substituted with nitronyl-nitroxide radicals

Stroh, Christophe,Mayor, Marcel,Von Haenisch, Carsten

, p. 3697 - 3703 (2007/10/03)

The synthesis of biphenyls substituted with nitronyl-nitroxide organic radicals is described. To investigate the Suzuki-type cross-coupling reaction conditions in the presence of the radical, a model compound 1 was prepared. The successful coupling was extended to cyano-functionalized, biphenylic, paramagnetic molecules. Both the ortho- and meta-iodophenyl-nitronyl-nitroxide radicals were used to synthesize radicals 2 and 3. The characterizations of the spin-labelled molecules obtained by this synthetic strategy include two X-ray crystal structures and magnetic measurements. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
