Check Digit Verification of cas no

The CAS Registry Mumber 420107-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,1,0 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 420107-87:
(8*4)+(7*2)+(6*0)+(5*1)+(4*0)+(3*7)+(2*8)+(1*7)=95
95 % 10 = 5
So 420107-87-5 is a valid CAS Registry Number.

Synthesis and study of the behavior of glycosylated gemini surfactants in aqueous media

Wathier,Polidori,Ruiz,Fabiano,Pucci

, p. 1588 - 1599 (2007/10/03)

The work reported herein deals with the synthesis and physico-chemical studies of a new kind of glycosylated non-ionic gemini surfactants. These compounds derive from tris(hydroxymethyl)aminomethane and bear hydro- or perfluorocarbon tails. The chemical structures of the spacer arm and hydrophobic tails were adjusted in order to specify their impact on the gemini surfactant behavior in aqueous media. The supramolecular systems they form were studied by TEM after negative staining. The length and the rigidity of the spacer arm seem to play a key role in the aggregation behavior of these surfactants in water. With the appropriate modifications, the formation of premicellar associations, micelles, vesicles or various aggregates can be observed.
