Check Digit Verification of cas no

The CAS Registry Mumber 33335-96-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,3 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 33335-96:
(7*3)+(6*3)+(5*3)+(4*3)+(3*5)+(2*9)+(1*6)=105
105 % 10 = 5
So 33335-96-5 is a valid CAS Registry Number.

Sulfonate-bonded tin complexes for the production of diphenyl carbonate

Lee, Hyunjoo,Bae, Jin Yong,Kwon, O-Sung,Kim, Sung Joon,Lee, Sang Deuk,Sik Kim, Hoon

, p. 1816 - 1820 (2004)

Various tin complexes including dibutyltin oxide and dibutyltin diacetate were tested for their activities in the transesterification between dimethyl carbonate (DMC) and phenol to produce diphenyl carbonate (DPC). The activities of tin complexes were significantly enhanced by the co-presence of alkyl or arylsulfonic acid, possibly due to the in situ formation of sulfonate-bonded tin complexes. Highly active triflate-bonded tin species, [Bu2Sn(OH) (OTf)]2 and [Bu2Sn(OAc)(OTf)]2, were isolated from the reaction of triflic acid with dibutyltin oxide and dibutyltin diacetate, and characterized by single crystal X-ray diffraction study.
