Check Digit Verification of cas no

The CAS Registry Mumber 66572-41-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,5,7 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 66572-41:
(7*6)+(6*6)+(5*5)+(4*7)+(3*2)+(2*4)+(1*1)=146
146 % 10 = 6
So 66572-41-6 is a valid CAS Registry Number.

, p. 6598 - 6601 (2015/11/09)

The Boulton-Katritzky reaction represents one of the most popular and efficient strategies used to realize azole-into-azole conversions. For example, under different experimental conditions, it allows the rearrangement of Z-arylhydrazones of 3-benzoyl-5-p

Mononuclear Heterocyclic Rearrangements. Part 13. Substituent Effects on the Rearrangement of Some Z-Arylhydrazones of 3-Benzoyl-5-phenyl-1,2,4-oxadiazole to 2-Aryl-4-benzoylamino-5-phenyl-1,2,3-triazoles in Benzene, Dioxane, Ethyl Acetate, Acetonitrile,

Frenna, Vincenzo,Vivona, Nicolo,Cannella, Luciano,Cousiglio, Giovanni,Spinelli, Domenico

, p. 1183 - 1188 (2007/10/02)

The effects of substituents in the aryl fragment of the Z-arylhydrazones of 3-benzoyl-5-phenyl-1,2,4-oxadiazole (1) on the rate of the title reaction have been studied at 313.15 K.The results indicate a changeover of mechanism with changing substituent: i
