Check Digit Verification of cas no

The CAS Registry Mumber 50728-05-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,7,2 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 50728-05:
(7*5)+(6*0)+(5*7)+(4*2)+(3*8)+(2*0)+(1*5)=107
107 % 10 = 7
So 50728-05-7 is a valid CAS Registry Number.

DER OXIDATIVE ABBAU VON THIOPHOSPHIN- THIOPHOSPHON- UND THIOPHOSPHORSAEUREESTERN MIT HYPOCHLORIT

Horner, Leopold,Gerhard, Joachim

, p. 13 - 22 (2007/10/02)

The thioesters R1R2P(X)SR (X = O, S) 1 to 4 are degradated oxidatively forming R1R2P(O)OH and R-SO3H.The influence of the following parameters on the oxidation course is investigated using standard conditions: pH, concentration of the hypochlorite, quality of the organic phase and cooperation of phase transfer catalysts and hypochlorite cations.The thioesters 1 to 4 are degradated by hypochlorite with different rates depending on the type of the ligands R1 and R2 and the employment of an optimal pH.An analytical evaluation is possible.
