p-Chlor-benzopersaeure-<α.α-dimethyl-benzylester>, also known as p-chlorobenzoic acid α,α-dimethylbenzyl ester, is a chemical compound with the molecular formula C15H15ClO2. It is a derivative of p-chlorobenzoic acid, where the hydrogen atoms on the benzyl group are replaced by methyl groups, resulting in a more stable and less reactive ester. p-Chlor-benzopersaeure-<α.α-dimethyl-benzylester> is characterized by its aromatic structure, with a chlorine atom attached to the para position of the benzene ring, and an ester group formed by the reaction of p-chlorobenzoic acid with α,α-dimethylbenzyl alcohol. It is used in various chemical synthesis processes, particularly in the production of pharmaceuticals and agrochemicals, due to its unique reactivity and stability.
The CAS Registry Mumber 3955-79-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,5 and 5 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 3955-79: (6*3)+(5*9)+(4*5)+(3*5)+(2*7)+(1*9)=121 121 % 10 = 1 So 3955-79-1 is a valid CAS Registry Number.
