(8*1)+(7*7)+(6*2)+(5*7)+(4*5)+(3*2)+(2*3)+(1*5)=141
141 % 10 = 1
So 172752-35-1 is a valid CAS Registry Number.

Sulphur-substituted Organotin Compounds. Part 8. Preparation and Reactions of 3-(p-Tolylthio)propyl- and 4-(p-Tolylthio)butyl-triphenyltin. Interactions with Tetracyanoethylene

Wardell, James L.,Wigzell, John McM.

, p. 2321 - 2326 (2007/10/02)

The reactions of SnPh3 (n= 3 or 4) with mercury(II) chloride, bromine and iodine lead to phenyl-tin bond cleavage.In contrast, reactions with methyl iodide provide SnPh3 and MeSC6H4Me-p.Charge-transfer adducts are formed between SnPh3 (n= 1-4) and tetracyanoethylene or p-bromoanil.The values of λmax. of the complexes indicate similar donor character for SnPh3 (n= 2,3, or 4); however, the compound SnPh3(CH2SC6H4Me-p) is a stronger donor.
