69314-23-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69314-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,3,1 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 69314-23:
(7*6)+(6*9)+(5*3)+(4*1)+(3*4)+(2*2)+(1*3)=134
134 % 10 = 4
So 69314-23-4 is a valid CAS Registry Number.

Metal Template Reactions. XXIII. Synthesis of Macrocyclic Amide and Ester complexes via 1,1'-Oxalylbisisatin
Black, David St. C.,Moss, G. Ian
, p. 129 - 142 (2007/10/02)
1,1'-Oxalylbisisatin (7) has been prepared and converted readily into a wide range of glyoxylic esters and amides (10) from which the macrocyclic metal complexes (11)-(16) have been obtained.
