Check Digit Verification of cas no

The CAS Registry Mumber 131602-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,6,0 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 131602-44:
(8*1)+(7*3)+(6*1)+(5*6)+(4*0)+(3*2)+(2*4)+(1*4)=83
83 % 10 = 3
So 131602-44-3 is a valid CAS Registry Number.

PAF-antagonists with phospholipid structure. Part 2: Phospholipids with heteroarene head groups and variation of the P-N-distance; synthesis, characterization and structure-activity relationships

Kertscher,Ostermann

, p. 708 - 711 (2007/10/02)

A series of 27 PAF-analogues with heteroarene head groups and variation of the P-N-distance on the C-3-position of the backbone were synthesized, and the PAF-antagonistic activity on human blood platelets in vitro was evaluated. Investigation of structure-activity relationships revealed that PAF-antagonistic activity is strongly influenced by the 4-(Dimethylamino)-pyridine as polar head base and the distance between phosphate group and onium center. Maximal activity was observed with a chain length of 3 or 4 methylene groups. Among the compounds tested, 1-O-Hexadecyl-2-n-propylpropan-1,3-diol-3-phosphoric acid-4'-[4-(dimethylamino)pyridinium]butylester was the most effective inhibitor in the in vitro assay (K(B) = 0,3 μmol/l).
