Riboflavin 4',5'-cyclic phosphate, also known as FAD, is a crucial coenzyme derived from riboflavin (vitamin B2). It plays a vital role in cellular metabolism by participating in various redox reactions, particularly in the electron transport chain. FAD is involved in the conversion of food into energy by facilitating the transfer of electrons between proteins in the mitochondria. This process is essential for the production of ATP, the primary energy currency of cells. Additionally, FAD contributes to the maintenance of healthy skin, eyes, and mucous membranes, and it is also involved in the metabolism of drugs and toxins. The cyclic phosphate structure of FAD allows it to bind to proteins, making it an integral component of several flavoproteins that are critical for cellular respiration and other metabolic pathways.
The CAS Registry Mumber 986-54-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,8 and 6 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 986-54: (5*9)+(4*8)+(3*6)+(2*5)+(1*4)=109 109 % 10 = 9 So 986-54-9 is a valid CAS Registry Number.
