21230-20-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21230-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21230-20:
(7*2)+(6*1)+(5*2)+(4*3)+(3*0)+(2*2)+(1*0)=46
46 % 10 = 6
So 21230-20-6 is a valid CAS Registry Number.

Kinetics of the Thermal Decomposition of Benzenesulfinyl Azide
Maricich, Tom J.,Angeletakis, Christos N.,Mjanger, Ragnvald
, p. 1928 - 1931 (1984)
Kinetic studies show that the thermal decomposition of benzenesulfinyl azide (2) follows first-order kinetics in the presence of a variety of substrates.The typical rate constant at 20 deg C was 3 x 10-3 s-1.In acetonitrile, ΔH(excit
