N-acetyl-3,5,3',5'-tetraiodo-O'-methyl-DL-thyronine, also known as liothyronine or Cytomel, is a synthetic thyroid hormone that plays a crucial role in regulating the body's metabolism. N-acetyl-3,5,3',5'-tetraiodo-O'-methyl-DL-thyronine is structurally similar to the naturally occurring hormone triiodothyronine (T3), which is produced by the thyroid gland. Liothyronine is used as a medication to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormones. It is also prescribed for patients with goiter, a swelling of the thyroid gland, and for those who have undergone thyroid surgery or radiation therapy. The medication helps to restore normal thyroid hormone levels, alleviate symptoms of hypothyroidism, and maintain overall metabolic health.
The CAS Registry Mumber 1955-14-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,5 and 5 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1955-14: (6*1)+(5*9)+(4*5)+(3*5)+(2*1)+(1*4)=92 92 % 10 = 2 So 1955-14-2 is a valid CAS Registry Number.
