Check Digit Verification of cas no

The CAS Registry Mumber 202476-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,4,7 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 202476-26:
104 % 10 = 4
So 202476-26-4 is a valid CAS Registry Number.

Syntheses of 2-(trifluoromethyl)-1,3-dicarbonyl compounds through direct trifluoromethylation with CF3I and their application to fluorinated pyrazoles syntheses

Ohtsuka, Yuhki,Uraguchi, Daisuke,Yamamoto, Kyoko,Tokuhisa, Kenji,Yamakawa, Tetsu

, p. 2636 - 2649 (2012/04/23)

Direct trifluoromethylation of 1,3-dicarbonyl compounds with CF 3I in the presence of a Fenton reagent in dimethylsulfoxide was investigated. 1,3-Diketones, 3-oxocarboxylates and 3-oxocarboxamides were readily trifluoromethylated at the methyle
