Check Digit Verification of cas no

The CAS Registry Mumber 119441-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,4,4 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 119441-65:
(8*1)+(7*1)+(6*9)+(5*4)+(4*4)+(3*1)+(2*6)+(1*5)=125
125 % 10 = 5
So 119441-65-5 is a valid CAS Registry Number.

Mononuclear Heterocyclic Rearrangements. Part 14. Rearrangement of Some Z-Arylhydrazones of 3-Benzoyl-5-phenylisoxazole to 2-Aryl-4-phenacyl-1,2,3-triazoles in Dioxane-Water

Frenna, Vincenzo,Vivona, Nicolo,Macaluso, Gabriella,Spinelli, Domenico,Consiglio, Giovanni

, p. 537 - 540 (2007/10/02)

The kinetics of the title reaction have been measured at various pS+ values.The results show the occurrence of general base catalysis and furnish information about substituent effects on the studied reaction.A reaction mechanism analogous to that proposed for the rearrangement of the arylhydrazones of 3-benzoyl-5-phenyl-1,2,4-oxadiazole is suggested.The reactivity of isoxazole derivatives is much lower than that of 1,2,4-oxadiazole derivatives.
