54431-18-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54431-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,4,3 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54431-18:
(7*5)+(6*4)+(5*4)+(4*3)+(3*1)+(2*1)+(1*8)=104
104 % 10 = 4
So 54431-18-4 is a valid CAS Registry Number.

Synthesis, computational studies and assessment of in vitro inhibitory activity of umbelliferon-based compounds against tumour-associated carbonic anhydrase isoforms IX and XII

Coumarins are widely diffused secondary metabolites possessing a plethora of biological activities. It has been established that coumarins represent a peculiar class of human carbonic anhydrase (hCA) inhibitors having a distinct mechanism of action involv

Photo-induced Reactions: Part IV-Studies on Photo Fries Migration of Some Coumarins

Kulshrestha, S.K.,Dureja, P.,Mukerjee, S.K.

, p. 1064 - 1067 (2007/10/02)

Photo-Fries migration as an alternative route to acylcoumarins has been investigated. 7-Acetoxy- and 7-furoyloxy-coumarins give 6-acylcoumarins as the major products in contrast to Lewis acid mediated Fries migration where 8-acyl derivatives are the major products.The benzoates on the other hand give 6- and 8-acylcoumarins in equal proportions.The method is not suitable for the preparation of long chain unsaturated acyl derivatives of coumarins because in such cases photolytic deesterification is the main route.
