The chemical compound "(iso-C4H9)2ClSnCHCHC6H5" is a complex organotin compound with a molecular formula that can be broken down as follows: "iso-C4H9" represents an isobutyl group, which is a branched chain of four carbon atoms, and there are two of these groups attached to the central tin (Sn) atom. The "Cl" indicates a chlorine atom, and "CHCH" represents a vinyl group, which is a double-bonded carbon chain. Finally, "C6H5" is a phenyl group, which is a benzene ring. (iso-C4H9)2ClSnCHCHC6H5 is likely to be a type of organotin stabilizer used in various industrial applications, such as in the production of polyvinyl chloride (PVC) to prevent degradation. The specific structure suggests that it has a diorganotin moiety with two isobutyl groups, a chloro group, and a phenyl group attached to a vinyl group, which is then bonded to the tin atom.
The CAS Registry Mumber 6774-72-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,7 and 4 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6774-72: (6*6)+(5*7)+(4*7)+(3*4)+(2*7)+(1*2)=127 127 % 10 = 7 So 6774-72-7 is a valid CAS Registry Number.
