145220-82-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 145220-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,2 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145220-82:
(8*1)+(7*4)+(6*5)+(5*2)+(4*2)+(3*0)+(2*8)+(1*2)=102
102 % 10 = 2
So 145220-82-2 is a valid CAS Registry Number.

Studies on nilvadipine. III. Synthesis of metabolites of nilvadipine and their related compounds

Satoh,Okumura,Shiokawa

, p. 1799 - 1807 (2007/10/02)

Nilvadipine (I), isopropyl 2-cyano-3-methoxycarbonyl-6-methyl-4-(3-nitrophenyl)-1,4-dihydropyridi ne-5-carboxylate, has a unique 1,4-dihydropyridine structure in that the substituents at all five positions of the nucleus differ from one another. It is an exellent calcium antagonist drug in terms of its potency, its duration of action and its selectivity in the blood vascular system. During the development of I, some metabolites were isolated from the urine and bile of both rats and dogs after oral administration. With data obtained from the metabolism of known 1,4-dihydropyridines at hand, we proposed the synthesis of a series of compounds (1-11) for comparison with the metabolites isolated from I as a method for structure determination. Indeed, of the compounds synthesized five of them (3-7) were found to coincide with the metabolites from both rat and dog urine and bile isolates.
