133595-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133595-51-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,9 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133595-51:
(8*1)+(7*3)+(6*3)+(5*5)+(4*9)+(3*5)+(2*5)+(1*1)=134
134 % 10 = 4
So 133595-51-4 is a valid CAS Registry Number.

Synthesis of spin-labelled 1,4-dihydropyridines and pyridines
Hankovszky,Sar,Hideg,Jerkovich
, p. 91 - 97 (2007/10/02)
1,4-Dihydropyridines spin-labelled with 5- and 6-membered nitroxyl radicals in positions 1-4 of the pyridine ring were synthesized. The oxidation of these dihydropyridines to pyridines with active manganese dioxide was investigated.
