99658-03-4 Usage

Biochem/physiol Actions

The corticotropin releasing factor (CRF) antagonist α-helical CRF [9-41] exhibits 10-fold higher affinity for rat CRF2α receptors over human CRF2α receptors. It has been used to elucidate the role of CRF in various physiological systems. In colonic epithelium, it abolishes CRF-induced changes in ion secretion, and significantly inhibits CRF-stimulated conductance. It antagonizes the CRF-induced proinflammatory degranulation of perivascular mast cells that are activated in response to acute psychological stress and CRF secretion.

Check Digit Verification of cas no

The CAS Registry Mumber 99658-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,5 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99658-03:
(7*9)+(6*9)+(5*6)+(4*5)+(3*8)+(2*0)+(1*3)=194
194 % 10 = 4
So 99658-03-4 is a valid CAS Registry Number.
