145970-12-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145970-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,9,7 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145970-12:
(8*1)+(7*4)+(6*5)+(5*9)+(4*7)+(3*0)+(2*1)+(1*2)=143
143 % 10 = 3
So 145970-12-3 is a valid CAS Registry Number.

, p. 617 - 626 (1993)
A series of 4-hydroxy-3-quinolinecarboxylic acid derivatives (6) and 4-hydroxy-2-oxo-1,2-dihydro-3-quinolinecarboxylic acid derivatives (7) were designed and synthesized as 5-HT3 receptor antagonists. Molecular modeling studies suggested that the 3-carbon
