Deformo- is a prefix used in chemistry to denote a specific type of chemical structure or compound. It is derived from the Latin word "deformare," which means to deform or change shape. In the context of chemistry, deformo- often refers to molecules that have undergone a structural change or deformation from their parent compound. This can involve alterations in the arrangement of atoms, the presence of additional functional groups, or changes in the overall geometry of the molecule. Deformo-compounds can exhibit different physical, chemical, and biological properties compared to their parent compounds, making them important in various fields such as pharmaceuticals, materials science, and environmental chemistry.
The CAS Registry Mumber 1897-28-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,9 and 7 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1897-28: (6*1)+(5*8)+(4*9)+(3*7)+(2*2)+(1*8)=115 115 % 10 = 5 So 1897-28-5 is a valid CAS Registry Number.
