Check Digit Verification of cas no
The CAS Registry Mumber 721448-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,1,4,4 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 721448-04:
(8*7)+(7*2)+(6*1)+(5*4)+(4*4)+(3*8)+(2*0)+(1*4)=140
140 % 10 = 0
So 721448-04-0 is a valid CAS Registry Number.

Synthesis of a novel dioxan sialic acid analog
Perron-Sierra, Fran?oise M.,Burbridge, Mike,Péan, Christophe,Tucker, Gordon C.,Casara, Patrick
, p. 4163 - 4166 (2007/10/03)
A preparative scale synthesis of a dioxan sialic acid analog was achieved from D-mannose. The conformation and the acidic character of this dioxan derivative, closely related to sialic acid, provides a scaffold for drug design.
