(4-Hydroxy-3-methoxy-phenoxy)-acetic acid, also known as vanillylmandelic acid (VMA), is a naturally occurring organic compound that serves as a metabolite of the neurotransmitter dopamine. It is formed through the enzymatic conversion of dopamine into norepinephrine, followed by the action of the enzyme catechol-O-methyltransferase (COMT) on norepinephrine, resulting in the formation of VMA. (4-hydroxy-3-methoxy-phenoxy)-acetic acid plays a crucial role in the diagnosis of certain neuroendocrine disorders, such as pheochromocytoma and neuroblastoma, as elevated levels of VMA can be detected in the urine of affected individuals. VMA is characterized by its molecular formula C10H12O5 and is an important biomarker in the assessment of catecholamine metabolism.

Check Digit Verification of cas no

The CAS Registry Mumber 34919-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,9,1 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34919-76:
(7*3)+(6*4)+(5*9)+(4*1)+(3*9)+(2*7)+(1*6)=141
141 % 10 = 1
So 34919-76-1 is a valid CAS Registry Number.
