107536-32-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 107536-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,5,3 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 107536-32:
(8*1)+(7*0)+(6*7)+(5*5)+(4*3)+(3*6)+(2*3)+(1*2)=113
113 % 10 = 3
So 107536-32-3 is a valid CAS Registry Number.

Unexpected Formation of Triarylbismuth Diformates in the Oxidation of Triarylbismuthines with Ozone at Low Temperatures

Suzuki, Hitomi,Ikegami, Tohru,Matano, Yoshihiro,Azuma, Nagao

, p. 2411 - 2416 (2007/10/02)

Oxidation of triphenylbismuthine 1 with ozone in toluene at -78 deg C gave, unexpectedly, a high yield of triphenylbismuth diformate 3, which was also obtainable as a minor product by a similar oxidation in ethyl acetate and acetone.An X-ray crystallographic study revealed that compound 3 has C2 symmetry, the geometry around the bismuth atom being best described as a distorted trigonal bipyramid as a result of strong intramolecular interaction between the bismuth and carbonyl oxygen atoms.Treatment of compound 3 with aqueous sodium acetate or halides readily converted it into the corresponding triphenylbismuth diacetate 5 or dihalides 7 - 9.
