Check Digit Verification of cas no
The CAS Registry Mumber 28306-73-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,0 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28306-73:
(7*2)+(6*8)+(5*3)+(4*0)+(3*6)+(2*7)+(1*3)=112
112 % 10 = 2
So 28306-73-2 is a valid CAS Registry Number.

Convenient, tandem and one-reaction vessel synthesis of mixed dialkylated 2-naphthols from 2-tetralone
Jha, Amitabh,Dimmock, Jonathan R.
, p. 293 - 296 (2003)
A convenient acid-catalyzed method for the synthesis of 1-alkyl-2-alkoxynaphthalenes by one-reaction vessel mixed alkylation of 2-tetralone, using aryl or alkyl aldehydes and alcohols followed by aromatization, is described.
