289038-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 289038-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,0,3 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 289038-69:
(8*2)+(7*8)+(6*9)+(5*0)+(4*3)+(3*8)+(2*6)+(1*9)=183
183 % 10 = 3
So 289038-69-3 is a valid CAS Registry Number.

Tuning selectivity in macrotricyclic carbohydrate receptors; CH → N mutations in aromatic spacers
Velasco, Trinidad,Lecollinet, Gregory,Ryan, Theo,Davis, Anthony P.
, p. 645 - 647 (2004)
Dipicolinoyl spacer groups are used to control the conformational and H-bonding properties of tricyclic carbohydrate receptors 3 and 4. Binding selectivities are changed in relation to all-isophthaloyl system 1b.
