67224-41-3 Usage
Description
ACTH (4-11) is a peptide fragment of adrenocorticotropic hormone (ACTH; ), a peptide hormone found in the brain that is involved in the biological stress response. ACTH (4-11) induces differentiation of melanocytes when used at a concentration of 1,000 nM. It inhibits angiotensin converting enzyme (ACE) activity in homogenized canine lung with an IC50 value of 24 μM. ACTH (4-11) has been used to determine substrate specificity of recombinant H. zea carboxypeptidase B enzyme (CPBHz).
Check Digit Verification of cas no
The CAS Registry Mumber 67224-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,2 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67224-41:
(7*6)+(6*7)+(5*2)+(4*2)+(3*4)+(2*4)+(1*1)=123
123 % 10 = 3
So 67224-41-3 is a valid CAS Registry Number.
