80547-87-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80547-87-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,4 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80547-87:
(7*8)+(6*0)+(5*5)+(4*4)+(3*7)+(2*8)+(1*7)=141
141 % 10 = 1
So 80547-87-1 is a valid CAS Registry Number.

Catechol O-Methyltransferase. 11. Inactivation by 5-Hydroxy-3-mercapto-4-methoxybenzoic Acid
Borchardt, Ronald T.,Huber, Joan A.
, p. 321 - 323 (2007/10/02)
5-Hydroxy-3-mercapto-4-methoxybenzoic acid was synthesized as a potential affinity-labeling reagent for catechol O-methyltransferase (COMT, EC 2.1.1.6).This compound was shown to produce noncompetitive inhibition of COMT when assayed in the presence or ab
