Check Digit Verification of cas no
The CAS Registry Mumber 20283-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,8 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20283-21:
(7*2)+(6*0)+(5*2)+(4*8)+(3*3)+(2*2)+(1*1)=70
70 % 10 = 0
So 20283-21-0 is a valid CAS Registry Number.

The kinetics of acid-catalyzed decomposition of decanepersulfonic acid
Zaripov,Mukhametzyanova,Safiullin,Komissarov
, p. 201 - 202 (1999)
The kinetics of thermal decomposition of decanepersulfonic acid (RSO2OOH, R = C10H21) in CCl4 in the presence of cyclohexanesulfonic and trifluoroacetic acids at 323-343 K was studied. The reaction has an autocatalytic character. The kinetics of consumption of the persulfonic acid is described by the equation -d[RSO2OOH]/df = k1[RSO2OOH] + k2[RSO2OOH] · [HX].
