29099-08-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 29099-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,0,9 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 29099-08:
(7*2)+(6*9)+(5*0)+(4*9)+(3*9)+(2*0)+(1*8)=139
139 % 10 = 9
So 29099-08-9 is a valid CAS Registry Number.

Hydrolysis of N-phenylalkanesulfinamides in aqueous mineral acids

Datta, Mrityunjoy,Buglass, Alan J.,Tillett, John G.

experimental part, p. 565 - 573 (2011/05/15)

The acid-catalyzed hydrolysis of N-phenylalkanesulfinamides (RSONHPh; 1, R = iPr; 2, R = tBu; 3, R = 1-adamantyl) has been studied in aqueous mineral acids. Hydrolysis was found to proceed via a slow spontaneous (uncatalyzed) pathway, an A-2 (bimolecular) acid-catalysis pathway, and an acid-dependent nucleophilic catalysis pathway, the last of which predominates in hydrobromic and hydrochloric acid solutions. A mechanistic switch over from A-2 to A-1 was detected for compounds 2 and 3 in concentrated sulfuric acid. Order of catalytic activity, effect of added salts, Arrhenius parameters, kinetic solvent isotope, and solvent effects are all consistent with the proposed mechanisms.

Electro-oxidative Neutral Deprotection of S-t-Butyl Thioates to give Carboxylic Acids

Kimura, Makoto,Matsubara, Shinichi,Sawaki, Yasuhiko

, p. 1619 - 1620 (2007/10/02)

t-Butyl thioates are proposed as a convenient protecting group for carboxylic acids, because their deprotection under neutral conditions can be attained by electro-oxidation using bromide salts as electrolytes in aqueous acetonitrile.
