Check Digit Verification of cas no

The CAS Registry Mumber 506444-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,6,4,4 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 506444-33:
(8*5)+(7*0)+(6*6)+(5*4)+(4*4)+(3*4)+(2*3)+(1*3)=133
133 % 10 = 3
So 506444-33-3 is a valid CAS Registry Number.

Synthesis of calix[4]crowns containing soft donor atoms and a study of their metal-cation binding properties: Highly selective receptors for Cu2+

Ashram, Muhammad

, p. 1662 - 1668 (2007/10/03)

Two new calix[4]arenethiacrown derivatives 1 and 2 in the cone conformation were synthesized by two different pathways in good yield. Their complexation properties toward alkali, alkaline earth and transition metal cations were studied in acetonitrile at 298.15 K using a conductometric titration technique. The selectivity for Cu2+ over other cations with these novel ligands was excellent.
