142891-74-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142891-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,9 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142891-74:
(8*1)+(7*4)+(6*2)+(5*8)+(4*9)+(3*1)+(2*7)+(1*4)=145
145 % 10 = 5
So 142891-74-5 is a valid CAS Registry Number.

1,4-dihydropyridines with etacrynic acid partial structure

Gorlitzer,Duwel

, p. 361 - 364 (2007/10/02)

Starting with the acetophenone 3 and the nitrobenzylidene compounds 4 and 5 as intermediates the 1,4-dihydropyridines (DHP) 6 and 7 possessing a dichlorophenoxyacetic acid substituent are prepared. The DHP's are oxidized to yield the pyridines 8 and 9. Th
