Check Digit Verification of cas no

The CAS Registry Mumber 198570-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,5,7 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 198570-91:
(8*1)+(7*9)+(6*8)+(5*5)+(4*7)+(3*0)+(2*9)+(1*1)=191
191 % 10 = 1
So 198570-91-1 is a valid CAS Registry Number.

Synthesis and reactions of new nitronyl nitroxides

Kálai, Tamás,Jeko, József,Szabó, Zoltán,Párkányi, László,Hideg, Kálmán

, p. 1049 - 1055 (1997)

Various new 2-substituted 4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazol-1-yloxyl 3-oxide mono- 1b, 7, 13a,b, 14, 15, 16, 17, 22 and biradicals 8, 9 were prepared. The nitronyl nitroxide functions were selectively reduced by Fe/HOAc to 1-hydroxyimidazoline derivatives 3b, 11, 21. The reductions by Zn/HCl led to imidazolines 4, 12. The nitronyl nitroxide functions remained inert when the 2-phenyl compound was nitrated by H2SO4/HNO3 to give nitrophenyl nitronyl nitroxide derivatives 13a,b, 14.
