Check Digit Verification of cas no
The CAS Registry Mumber 25946-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,4 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25946-69:
(7*2)+(6*5)+(5*9)+(4*4)+(3*6)+(2*6)+(1*9)=144
144 % 10 = 4
So 25946-69-4 is a valid CAS Registry Number.

Regioselective nucleophilic substitution of 5-bromo-2-methoxytropone
Sato, Ohki,Nitta, Ai,Yamamoto, Ami
, p. 644 - 650 (2015/02/05)
The reaction of 5-bromo-2-methoxytropone with O- and N-nucleophiles, such as ethanol/potassium carbonate, sodium hydroxide, diethylamine, propylamine, p-chloroaniline/triethylamine, and p-phenylenediamine/triethylamine, gave corresponding 2-O- and 2-N-substituted troponoids. Alkyl diamines reacted with the substrate to produce bis(2-aminotropone)s. In the case of S-nucleophiles as 1-propanethiol, thiophenol, and 4-aminothiophenol with a base, the regioselective substitution at the 5-position occurred. Halogenation reagents, triphenyldibromophosphorane and its dichloro analogue, furnished 2,5-dibromo- and 2,5-dichlorotropones, respectively.
