21127-57-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21127-57-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,2 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21127-57:
(7*2)+(6*1)+(5*1)+(4*2)+(3*7)+(2*5)+(1*7)=71
71 % 10 = 1
So 21127-57-1 is a valid CAS Registry Number.

Studies of Sulfinyl Radicals. 1. Thermal Decompositions of Benzhydryl p-Tolyl Sulfoxide and Benzhydryl Methyl Sulfoxide

Mizuno, Hajime,Matsuda, Minoru,Iino, Masashi

, p. 520 - 525 (1981)

The kinetics and mechanism of the thermal decompositions of benzhydryl p-tolyl sulfoxide (BTSO) and benzhydryl methyl sulfoxide (BMSO) were studied.Product analysis, ESR, and CIDNP results showed that both sulfoxides gave p-toluenesulfinyl and methanesulfinyl radicals, respectively, by the scission of carbon-sulfur bonds at 100-130 deg C.The presence of a small amount of a base such as pyridine has been found to suppress the formation of other products than the coupling products (the corresponding thiosulfonates and tetraphenylethane), which may be formed by ionic reactions of BTSO and BMSO.The mechanism of BTSO decomposition is complex, since it is in equilibrium with benzhydryl p-toluenesulfenate (BTSN) at 100-130 deg C.On the other hand, BMSO, showing simple decomposition behavior, indicated that the decomposition rates decreased on the addition of hydroxylic solvents.
