Check Digit Verification of cas no
The CAS Registry Mumber 951-02-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 951-02:
(5*9)+(4*5)+(3*1)+(2*0)+(1*2)=70
70 % 10 = 0
So 951-02-0 is a valid CAS Registry Number.

Oxygen transfer reactions. 2. A comparison of the reactions of ruthenium tetroxide, chromyl chloride, and permanganate with thianthrene 5-oxide
May,Yee,Lee
, p. 2249 - 2254 (2007/10/02)
Products obtained from the oxidation of thianthrene 5-oxide, SSO, have been used to compare oxygen transfer mechanisms for three high-valent transition metals. Oxidation of SSO by benzyltriethylammonium permanganate in methylene chloride gives the corresponding sulfone, thianthrene 5,5-dioxide (SSO2), as the exclusive product. Oxidation of SSO by ruthenium tetroxide also gives SSO2 as the predominant product along with minor amounts of the disulfoxide, thianthrene 5,10-dioxide (SOSO). However, the converse is observed when chromyl chloride is used as the oxidant; SOSO is the major product. It is suggested that oxygen transfers from permanganate and ruthenium tetroxide are initiated by complexation between the central metal atom and the oxygen end of the S=O dipole, while oxidation by chromyl chloride is likely initiated by an alternative mechanism, possibly a single electron transfer.

The products formed by the reaction of benzenethiols with diketene in the presence of H2SO4 are (E)-β-(arylthio)crotonic acids (2) and/or isomeric (Z)-β-(arylthio)crotonic acids and not, as has been reported, S-phenyl-3-oxobutanethioates (1).Compounds 1a-k, as the precursor of thiocoumarins, were prepared from benzenethiols and diketene in the presence of triethylamine.The reaction of 1 with various condensing agents has been examined to prepare 2H-1-benzothiopyran-2-ones (thiocoumarins).It is found that 4-methyl(thiocoumarins) were conveniently prepared by thereaction of 1 with anhydrous aluminium chloride in yields of 16-48percent.When 1 was treated with PPA, isomeric 2-methyl(thiochromones) were preferentially obtained in yields of 5-66percent, and compound 2 was isolated as an intermediate.The spectral characteristics of 4-methyl(thiocoumarins) have also been described.
