263159-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263159-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,1,5 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 263159-70:
(8*2)+(7*6)+(6*3)+(5*1)+(4*5)+(3*9)+(2*7)+(1*0)=142
142 % 10 = 2
So 263159-70-2 is a valid CAS Registry Number.

Cleft-type diamidinium receptors for dicarboxylate binding in protic solvents
Sebo, Lubomir,Schweizer, Bernd,Diederich, Francois
, p. 80 - 92 (2007/10/03)
A series of potential cleft-type receptors for dicarboxylate substrates were prepared by attachment of two phenylamidinium ions to either naphthalene or 1,1'-binaphthalene scaffolds. Their synthesis (Schemes 1-4) involved the Pd0-catalyzed cros
