DL-erythro-1,3-Dihydroxy-2-amino-eikosan, also known as DL-erythro-Dihydrosphingosin-C20, is a naturally occurring sphingosine derivative with the chemical formula C20H43NO3. It is a key component in the synthesis of complex sphingolipids, which are essential for maintaining cell membrane integrity and function. DL-erythro-1,3-Dihydroxy-2-amino-eikosan; DL-erythro-Dihydrosphingosin-C20 is characterized by its unique structure, featuring a long-chain hydrocarbon backbone with two hydroxyl groups at the 1 and 3 positions, and an amino group at the 2 position. DL-erythro-Dihydrosphingosin-C20 plays a crucial role in various biological processes, including cell signaling, and is involved in the regulation of cellular responses to stress and injury. Its presence is particularly significant in the nervous system, where it contributes to the formation and maintenance of myelin sheaths around nerve fibers.
The CAS Registry Mumber 3530-52-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,3 and 0 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3530-52: (6*3)+(5*5)+(4*3)+(3*0)+(2*5)+(1*2)=67 67 % 10 = 7 So 3530-52-7 is a valid CAS Registry Number.
