Check Digit Verification of cas no
The CAS Registry Mumber 2388-43-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,8 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2388-43:
(6*2)+(5*3)+(4*8)+(3*8)+(2*4)+(1*3)=94
94 % 10 = 4
So 2388-43-4 is a valid CAS Registry Number.

Syntheses of Calixnaphthalenes Derived from 1-Naphthol
Georghiou, Paris E.,Ashram, Muhammad,Li, Zhaopeng,Chaulk, Steven G.
, p. 7284 - 7289 (1995)
Using a convergent synthetic strategy, the synthesis of the previously elusive C4ν-symmetrical calixnaphthalene from 1-naphthol is described.Using other independent convergent routes, syntheses of the other three isomeric calixnaphthalenes originally formed from the direct base-catalyzed condensation of formaldehyde with 1-naphthol are also described.All of these methods involved either a TiCl4- or TFA-assisted coupling reaction to achieve the cyclization steps.A mechanism is proposed to account for the formation of the original three isomeric calixnaphthalenes from the base-catalyzed condensation of formaldehyde with 1-naphthol.
