43001-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 43001-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,0,0 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 43001-55:
(7*4)+(6*3)+(5*0)+(4*0)+(3*1)+(2*5)+(1*5)=64
64 % 10 = 4
So 43001-55-4 is a valid CAS Registry Number.

A colormetric assay for catechol-O-methyltransferase
Bailey, Karl,Cowling, Rebecca,Tan, Eng Wui,Webb, Daniel
, p. 595 - 601 (2007/10/03)
A series of catechol diazo dyes were synthesized and tested as substrates for the enzyme catechol-O-methyltransferase (COMT) with the aim of developing a sensitive HPLC assay method using visible wavelength light detection. A method was developed which al
