64421-69-8 Usage
General Description
PTH (44-68) (HUMAN) is a polypeptide hormone derived from parathyroid hormone (PTH) that plays a crucial role in regulating calcium and phosphate levels in the blood. This peptide contains the amino acids 44-68 from the N-terminal region of human PTH. PTH (44-68) is known to have both anabolic and catabolic effects on bone metabolism, stimulating bone formation and resorption. It also acts on the kidneys to increase calcium reabsorption and phosphate excretion. Additionally, PTH (44-68) has been shown to have potential therapeutic effects in treating osteoporosis and other bone-related diseases. Overall, PTH (44-68) is an important regulator of calcium and phosphate homeostasis with potential implications for medical treatment and research.
Check Digit Verification of cas no
The CAS Registry Mumber 64421-69-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,2 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 64421-69:
(7*6)+(6*4)+(5*4)+(4*2)+(3*1)+(2*6)+(1*9)=118
118 % 10 = 8
So 64421-69-8 is a valid CAS Registry Number.
