Check Digit Verification of cas no

The CAS Registry Mumber 110426-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,4,2 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 110426-49:
(8*1)+(7*1)+(6*0)+(5*4)+(4*2)+(3*6)+(2*4)+(1*9)=78
78 % 10 = 8
So 110426-49-8 is a valid CAS Registry Number.

BESTIMMUNG DER IONENPAAR-BASIZITAT VON LITHIUM- UND KALIUMAMIDEN

Ahlbrecht, Hubertus,Schneider, Gunther

, p. 4729 - 4742 (2007/10/02)

Ion pair basicities of lithio and potassio salts of some secondary amines were determined by equilibration with benzyl compounds.With these bases it is possible to span a range of about 19 pK-units from pK = 27 up to 46.The structural dependence of thermodynamic as well as kinetic basicity is discussed.Some new effective amide bases for preparative purposes are recommended.For the first time the pK-value of toluene has been determined by direct equilibration.It amounts to 40.7 in tetrahydrofuran.
