Check Digit Verification of cas no

The CAS Registry Mumber 1638211-20-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,8,2,1 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1638211-20:
(9*1)+(8*6)+(7*3)+(6*8)+(5*2)+(4*1)+(3*1)+(2*2)+(1*0)=147
147 % 10 = 7
So 1638211-20-7 is a valid CAS Registry Number.

Synthesis of ranolazine derivatives containing the (1S,4S)-2,5- diazabicyclo[2.2.1]heptane moiety and their evaluation as vasodilating agents

López-Ortiz, Manuel,Monsalvo, Ivan,Demare, Patricia,Paredes, Cristina,Mascher, Dieter,Hernández, Carlos,Hernández, Marcos,Regla, Ignacio

, p. 710 - 720 (2014/06/09)

Two diazabicyclic analogues of ranolazine, (S,S,S)-5 and (S,S,R)-5, and their epimeric mixture were synthesized. Furthermore, their vasomotor effects on rat aorta rings precontracted with phenylephrine were analyzed. These compounds showed vasodilating effects significantly greater than ranolazine. The vasodilating activities of these analogues have two components, one that depends on the endothelium, due to the release of NO, and another one due to a direct effect on the vascular smooth muscle. The compounds [(S,S,S)(S,S,R)]-5 and (S,S,R)-5 induce, in a manner similar to ranolazine, the release of a prostanoid from the cyclooxygenase pathway, whose vasoconstrictor effect is masked by the predominant vasodilation induced by these compounds.
