Oxytocin, also known as Lys(8)-oxytocin, is a hormone and neuropeptide that plays a crucial role in various physiological processes, including childbirth, lactation, and social bonding. It is produced in the hypothalamus and released into the bloodstream by the posterior pituitary gland. The chemical structure of oxytocin consists of a nine-amino-acid peptide chain, with the amino acid lysine at the eighth position, hence the name Lys(8)-oxytocin. This hormone is known for its ability to induce uterine contractions during labor, facilitate milk ejection during breastfeeding, and promote trust, empathy, and social recognition in humans and animals. Additionally, oxytocin has been implicated in the regulation of stress response, anxiety, and depression, making it a significant molecule in the field of neuroscience and endocrinology.

4273-93-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4273-93-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.Calculate Digit Verification of CAS Registry Number 4273-93:
(6*4)+(5*2)+(4*7)+(3*3)+(2*9)+(1*3)=92
92 % 10 = 2
So 4273-93-2 is a valid CAS Registry Number.
