139598-41-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139598-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,9 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139598-41:
(8*1)+(7*3)+(6*9)+(5*5)+(4*9)+(3*8)+(2*4)+(1*1)=177
177 % 10 = 7
So 139598-41-7 is a valid CAS Registry Number.

Reduction of antimony(V) by dithiophosphinates and the crystal structure of dimeric diphenylantimony(III) dimethyldithiophosphinate

Gibbons, Martin N.,Sowerby, D. Bryan,Silvestru, Christian,Haiduc, Ionel

, p. 4573 - 4578 (1996)

Reactions between three diorganodithiophosphinates and diphenylantimony(V) bromide oxide (SbPh2OBr)2, led to antimony reduction while dithiophosphinate oxidation followed a complex path varying in detail with the nature of the organic groups on dithiophosphinate. Antimony(III) dithiophosphinates, SbPh2(S2PR2) where R = Me, Et and Ph, have been isolated and characterised and an X-ray structure determination for the methyl derivative shows weakly associated dimers in the solid state, intermediate between those in (SbPh2S2PPh2)2 and [Sb(4-MeC6H4)2S2PEt]2.
