Urea, N,N'-bis(3,5-dichloro-2,4,6-trimethylphenyl)-, also known as 3,3'-Dichloro-2,2',4,4',6,6'-hexamethyl-4,4'-biphenylurea or DCMU, is a chemical compound with the molecular formula C17H18Cl2N2O. It is a white crystalline solid that is widely used as a potent inhibitor of photosynthesis in plants, specifically targeting the photosystem II (PSII) complex. DCMU works by binding to the D1 protein of the PSII complex, preventing the transfer of electrons and inhibiting the light-dependent reactions of photosynthesis. Urea, N,N'-bis(3,5-dichloro-2,4,6-trimethylphenyl)- is commonly used in research to study the mechanisms of photosynthesis and to control plant growth in various applications.
The CAS Registry Mumber 63447-11-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,4,4 and 7 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 63447-11: (7*6)+(6*3)+(5*4)+(4*4)+(3*7)+(2*1)+(1*1)=120 120 % 10 = 0 So 63447-11-0 is a valid CAS Registry Number.
