Check Digit Verification of cas no
The CAS Registry Mumber 25986-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,8 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25986-80:
(7*2)+(6*5)+(5*9)+(4*8)+(3*6)+(2*8)+(1*0)=155
155 % 10 = 5
So 25986-80-5 is a valid CAS Registry Number.

-
, (2008/06/13)
An ester of a carboxylic acid is prepared via a transesterification reaction which comprises reacting a lower alkyl ester of carboxylic acid with a higher alkyl alcohol in the presence of a catalyst consisting of a hafnium chelate derived from hafnium tetrachloride, bis(alkoxide)hafnium dichlorides, or hafnium tetraalkoxides in the presence of 1,3-dicarbonyl compounds.
