Check Digit Verification of cas no

The CAS Registry Mumber 3172-00-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,7 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3172-00:
(6*3)+(5*1)+(4*7)+(3*2)+(2*0)+(1*0)=57
57 % 10 = 7
So 3172-00-7 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.
