Uses

PL-AAEM Resin, is a styrene/methacrylate copolymer matrix. It is a scavenger resin designed to selectively remove the primary amines in the presence of secondary amines.

Check Digit Verification of cas no

The CAS Registry Mumber 34500-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,5,0 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 34500-18:
(7*3)+(6*4)+(5*5)+(4*0)+(3*0)+(2*1)+(1*8)=80
80 % 10 = 0
So 34500-18-0 is a valid CAS Registry Number.

Nimodipine: Synthesis and metabolic pathway

Meyer,Wehinger,Bossert,Scherling

, p. 106 - 112 (2007/10/02)

Key step of the synthesis of the calcium antagonistic cerebral vasodilator (±) isopropyl-2-methoxyethyl 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedicarboxylate (Bay e 9736, nimodipine) is the cyclising Michael addition. A pharmacokinetic study with 14C-nimodipine in the rat revealed as major metabolites the dihydropyridines as well as the pyridines. A potential metabolic pathway is discussed involving ether cleavage and oxidation to the pyridine form as primary biotransformation steps. Reference metabolites were synthesized using 1,4-dihydropyridines with appropriate functionalities as precursors.
