The chemical "7-hydroxy-2-p-tolyl-chromenylium" is a flavonoid derivative, which is a type of organic compound found in plants. It has a structure that includes a hydroxyl group at the 7th position, a para-tolyl group (a methyl group attached to the para position of a phenyl ring) at the 2nd position, and a chromenylium ion, which is a positively charged aromatic ring system. On the other hand, "2,4,6-trinitro-3-trifluoromethyl-phenolate" is an anion derived from a phenol compound that has been modified with three nitro groups at the 2nd, 4th, and 6th positions, and a trifluoromethyl group at the 3rd position. 7-hydroxy-2-p-tolyl-chromenylium; 2,4,6-trinitro-3-trifluoromethyl-phenolate is known for its strong electron-withdrawing properties due to the presence of the nitro and trifluoromethyl groups, which can significantly influence its reactivity and stability. Both of these chemicals are examples of complex organic molecules with unique structural features and potential applications in various fields, such as pharmaceuticals, agrochemicals, or materials science.
The CAS Registry Mumber 475-15-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 5 respectively; the second part has 2 digits, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 475-15: (5*4)+(4*7)+(3*5)+(2*1)+(1*5)=70 70 % 10 = 0 So 475-15-0 is a valid CAS Registry Number.
