108891-76-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108891-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,8,9 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 108891-76:
(8*1)+(7*0)+(6*8)+(5*8)+(4*9)+(3*1)+(2*7)+(1*6)=155
155 % 10 = 5
So 108891-76-5 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.
