5,6,7,8-tetrahydro-pteroic acid (THPA) is a reduced form of pteroic acid, a naturally occurring compound found in plants and fungi. It is a heterocyclic molecule with a pteridine ring system and a glutamic acid side chain. THPA plays a crucial role in the biosynthesis of folic acid, a vital B-vitamin that is essential for DNA synthesis, cell division, and various metabolic processes in the human body. Due to its importance in folic acid production, THPA has been studied for its potential applications in pharmaceuticals, particularly in the development of anti-cancer drugs and as a supplement to prevent birth defects caused by folic acid deficiency.
The CAS Registry Mumber 4299-32-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,9 and 9 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4299-32: (6*4)+(5*2)+(4*9)+(3*9)+(2*3)+(1*2)=105 105 % 10 = 5 So 4299-32-5 is a valid CAS Registry Number.
