17976-83-9 Usage
General Description
2,3-Dimethoxy-5-hydroxy-6-phytyl-1,4-benzoquinone, also known as plastoquinone-9, is a naturally occurring compound found in plants and photosynthetic bacteria. It is a vital component of the electron transport chain in photosynthesis, serving as an electron carrier between photosystem II and cytochrome b6f complex. This redox-active molecule plays a crucial role in transferring electrons and protons across the thylakoid membrane, ultimately contributing to the production of ATP and NADPH during photosynthesis. Plastoquinone-9 is a potent antioxidant, protecting the chloroplast from oxidative damage by scavenging harmful free radicals. Its phytyl tail anchors the molecule in the thylakoid membrane, ensuring its efficient function in the photosynthetic process. Due to its biological significance, plastoquinone-9 is of great interest in pharmaceutical and agricultural research as a potential target for enhancing crop productivity and developing new therapeutic agents.
Check Digit Verification of cas no
The CAS Registry Mumber 17976-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,7 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 17976-83:
(7*1)+(6*7)+(5*9)+(4*7)+(3*6)+(2*8)+(1*3)=159
159 % 10 = 9
So 17976-83-9 is a valid CAS Registry Number.
