Tri-n-butylantimondichlorid, also known as tributyltin dichloride, is an organotin compound with the chemical formula (C4H9)3SnCl2. It is a colorless, oily liquid that is soluble in organic solvents and has a pungent odor. Tri-n-butylantimondichlorid is primarily used as a catalyst in the production of polyurethane foams and as a heat stabilizer for PVC. It is also employed as a fungicide and a biocide in various applications, such as antifouling paints for ships and as a wood preservative. Due to its toxicity and potential environmental impact, the use of tributyltin compounds has been restricted or banned in many countries.

Check Digit Verification of cas no

The CAS Registry Mumber 16585-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,8 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16585-54:
(7*1)+(6*6)+(5*5)+(4*8)+(3*5)+(2*5)+(1*4)=129
129 % 10 = 9
So 16585-54-9 is a valid CAS Registry Number.

Reactions of some trialkyls of phosphorus, arsenic, or antimony with some organohalophosphines, -arsines, or -stibines

Summers, Jack C.,Sisler, Harry H.

, p. 862 - 869 (2008/10/08)

The reactions of a series of alkyl- and arylphosphines, -arsines, or -stibines with a variety of halo- and haloalkyl- (or haloaryl-) phosphines, -arsines, or -stibines have been studied. It has been shown that in most instances the formation of adducts of the general formula RnMX3-n·yM′R′3 occurs and that in many instances these adducts decompose to give M-M bonded compounds plus R′3M′X2. It was further shown by electrical conductance and proton magnetic resonance data that a number of these adducts are ionic in solution.
