Check Digit Verification of cas no

The CAS Registry Mumber 16804-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,0 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16804-20:
(7*1)+(6*6)+(5*8)+(4*0)+(3*4)+(2*2)+(1*0)=99
99 % 10 = 9
So 16804-20-9 is a valid CAS Registry Number.

New synthetic approach to peri-hydroxy-substituted carbonyl acenaphthene derivatives

Bezuglov,Minyaeva,Mezheritskii

, p. 353 - 357 (2008/12/22)

A new approach to the synthesis of peri-hydroxyacenaphthoyl compounds has been developed on the basis of acylation (formylation) of 5- acyloxyacenaphthenes. The reactions are accompanied by formation of the corresponding 3- and 8-acyl-substituted isomers. In some cases, the latter can be isolated and identified by 1H NMR spectroscopy.
