16432-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16432-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,3 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16432-90:
(7*1)+(6*6)+(5*4)+(4*3)+(3*2)+(2*9)+(1*0)=99
99 % 10 = 9
So 16432-90-9 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
