Tributyltinhydride, also known as TBTH, is an organotin compound with the chemical formula (C4H9)3SnH. It is a colorless, oily liquid that is highly toxic and has a pungent odor. TBTH is primarily used as a catalyst in various chemical reactions, such as the hydrosilylation of alkenes and alkynes, and as a reagent in the synthesis of other organotin compounds. Due to its toxicity and potential environmental impact, the use of tributyltin compounds has been restricted in many countries.
The CAS Registry Mumber 688-76-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 8 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 688-76: (5*6)+(4*8)+(3*8)+(2*7)+(1*6)=106 106 % 10 = 6 So 688-76-6 is a valid CAS Registry Number.
