Check Digit Verification of cas no
The CAS Registry Mumber 55108-28-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,1,0 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55108-28:
(7*5)+(6*5)+(5*1)+(4*0)+(3*8)+(2*2)+(1*8)=106
106 % 10 = 6
So 55108-28-6 is a valid CAS Registry Number.

Claisen condensations of 1,3-diacetyl-2-hydroxy-5-methylbenzene with esters gave two new outstanding tetraketone ligands. The optimized procedure was developed into a multi-grams scale preparation of 1,3-bis-(3-oxo-3-phenyl-propionyl)-2-hydroxy-5-methylbe
