Check Digit Verification of cas no

The CAS Registry Mumber 1335144-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,1,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1335144-49:
(9*1)+(8*3)+(7*3)+(6*5)+(5*1)+(4*4)+(3*4)+(2*4)+(1*9)=134
134 % 10 = 4
So 1335144-49-4 is a valid CAS Registry Number.

Synthesis and structural features of sulfur-substituted calix[4]pyrrole for a bottom-up control of the substrate-directed self-assembly of supramolecular structures

Barattucci, Anna,Bonaccorsi, Paola,Cafeo, Grazia,Kohnke, Franz H.,Papalia, Teresa

, p. 7548 - 7556 (2011/10/12)

The synthesis of six new calix[4]pyrroles, containing sulfur-substituted phenylene units is reported. Halogen-anions and organic aromatic mono- and bis-anions have been selected to explore the formation of host-guest complexes and the possible self-assembly of multi-component structures with the six calixpyrroles. The type of aryl substitution modulates the strength of binding and the selectivity towards different anions and, in some cases, the combination of receptors and bis-anionic precursors, offers a way to build systems in which capsular assemblies are observed.
