The chemical compound "(C4H9)3SnOC(CH3)(C3H7)CH(CH3)COOCH3" is a complex organotin compound with a molecular formula that can be broken down into its constituent parts for better understanding. It consists of a tin (Sn) atom at the center, surrounded by three butyl (C4H9) groups, which are alkyl chains with four carbon atoms each. Attached to the tin is an oxygen atom (O), which is part of an ester group. The ester group is formed by a methyl group (CH3), a propyl group (C3H7), a methylene group (CH2), and a methyl group (CH3), which together form the alkyl chain of the ester. The terminal part of the ester is a methoxy group (OCH3), which is a methyl group attached to an oxygen atom. (C4H9)3SnOC(CH3)(C3H7)CH(CH3)COOCH3 is likely to be used in industrial applications due to its organotin nature, which can have various properties such as being used as a catalyst, stabilizer, or in the production of certain types of plastics and coatings.
The CAS Registry Mumber 66957-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 66957-25: (7*6)+(6*6)+(5*9)+(4*5)+(3*7)+(2*2)+(1*5)=173 173 % 10 = 3 So 66957-25-3 is a valid CAS Registry Number.
