143871-17-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143871-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,7 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143871-17:
(8*1)+(7*4)+(6*3)+(5*8)+(4*7)+(3*1)+(2*1)+(1*7)=134
134 % 10 = 4
So 143871-17-4 is a valid CAS Registry Number.

An optically pure 1,4-dihydropyridine from a resolution catalysed by rabbit liver esterase
Reeve,Crout,Cooper,Fray
, p. 785 - 794 (2007/10/02)
The kinetic resolution of the precursor of the dihydropyridine UK-74,505, 1, an antagonist of platelet activating factor, is described, in which rabbit liver esterase was used to catalyse the hydrolysis of an ester function linked to the chiral centre via
