OXALYL BROMIDE is a clear yellow to yellow-green liquid that is commonly used in various synthetic applications and chemical reactions. It is known for its ability to facilitate the formation of carbon-substituted iminium salts and is involved in the synthesis of mutasynthons, which are added to cultures of A. pretiosum for mutasynthetic generation of ansamitocin derivatives. Additionally, OXALYL BROMIDE plays a role in the formation of oxalic acid from hydroxyl radical substitutions and is used in the cyclization process to produce CRF1 receptor antagonists. It is also utilized in the preparation, optical, and electrochemical studies of thiophene end-capped olig(2,3-alkylthieno[3,4-b]pyrazine) and in the asymmetrical synthesis of glycosyl chlorides and bromides.

Biochem/physiol Actions

Leptin is a hormone produced primarily in adipocytes, although leptin mRNA has also been identified in placenta and fetal tissues, gastric tissue and liver. Its primary site of action appears to be on neurons in the hypothalamus that are involved in regulating energy balance, appetite, and body weight. Leptin increases the production of nitric oxide in endothelial cells and stimulates angiogenesis in vitro and in vivo.Human and mouse leptin share ~84% sequence identity.

Check Digit Verification of cas no

The CAS Registry Mumber 15219-34-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,1 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 15219-34:
(7*1)+(6*5)+(5*2)+(4*1)+(3*9)+(2*3)+(1*4)=88
88 % 10 = 8
So 15219-34-8 is a valid CAS Registry Number.
