Check Digit Verification of cas no

The CAS Registry Mumber 188263-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,2,6 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 188263-54:
(8*1)+(7*8)+(6*8)+(5*2)+(4*6)+(3*3)+(2*5)+(1*4)=169
169 % 10 = 9
So 188263-54-9 is a valid CAS Registry Number.

The effect of chromenone receptors on the selectivity of the reaction between pyrrolidine and 5-hydroxymethyl-2-(5H)-furanone

Raposo, Cesar,Almaraz, Marta,Martin, Mercedes,Alcazar, Victoria,Caballero, M. Cruz,Morán, Joaquin R.

, p. 173 - 174 (1997)

Several chromenone-based receptors have been prepared. Despite the self-association of these hosts in CDCl3 they are able to bind hydroxymethylfuranones with a Kass of around 1000 M-1. These compounds are able to accelerate the rate of the reaction of butenolide with pyrrolidine together with the increase of the selectivity.
