Xanthylium perchlorate, also known as 9,10-dimethyl-9,10-dihydroacridinium perchlorate, is a chemical compound with the molecular formula C13H14ClNO4. It is a derivative of the xanthene family, characterized by its yellow color and a tricyclic structure. Xanthylium perchlorate is a strong acid and is commonly used as a reagent in analytical chemistry for the detection of certain metal ions, particularly in the determination of aluminum. It is also employed in the synthesis of various organic compounds and pharmaceuticals. Due to its perchlorate anion, xanthylium perchlorate can be hazardous and requires careful handling, as perchlorates are known to be potentially explosive under certain conditions.
The CAS Registry Mumber 2567-19-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,6 and 7 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2567-19: (6*2)+(5*5)+(4*6)+(3*7)+(2*1)+(1*9)=93 93 % 10 = 3 So 2567-19-3 is a valid CAS Registry Number.
