121235-98-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121235-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,3 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 121235-98:
(8*1)+(7*2)+(6*1)+(5*2)+(4*3)+(3*5)+(2*9)+(1*8)=91
91 % 10 = 1
So 121235-98-1 is a valid CAS Registry Number.

First observation of monomer and dimer radical cation upon photoreduction of cyanopyridinium derivatives in solution by electron spin resonance and absorption spectroscopy

Park, Sang Hyun,Kawai, Hideki,Nagamura, Toshihiko

, p. 11987 - 11991 (2002)

The monomer radical and the dimer radical cation of cyanopyridinium derivatives have been studied by absorption and electron spin resonance (ESR) spectroscopies at room temperature in acetonitrile upon steady photolysis. The stable cyanopyridinyl radical
