Triphenyl(phenylethynyl)stannane, also known as (phenylethynyl)triphenylstannane, is an organostannane compound with the chemical formula C22H17Sn. It is a colorless solid that is sensitive to air and moisture. triphenyl(phenylethynyl)stannane is characterized by a central tin atom bonded to three phenyl groups and one phenylethynyl group. The phenylethynyl group is a phenyl ring with a triple bond between two carbon atoms, which provides unique electronic properties to the molecule. Triphenyl(phenylethynyl)stannane is used in organic synthesis, particularly in the formation of carbon-carbon bonds through cross-coupling reactions, and as a reagent in the synthesis of various organic compounds. Due to its reactivity, it is typically handled under an inert atmosphere to prevent unwanted side reactions.

1247-08-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1247-08-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1247-08:
(6*1)+(5*2)+(4*4)+(3*7)+(2*0)+(1*8)=61
61 % 10 = 1
So 1247-08-1 is a valid CAS Registry Number.
