Check Digit Verification of cas no
The CAS Registry Mumber 20217-30-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,1 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20217-30:
(7*2)+(6*0)+(5*2)+(4*1)+(3*7)+(2*3)+(1*0)=55
55 % 10 = 5
So 20217-30-5 is a valid CAS Registry Number.

Reaction of Azide Radicals with Aromatic Compounds. Azide as a Selective Oxidant
Alfassi, Zeev B.,Schuler, Robert H.
, p. 3359 - 3363 (1985)
In basic aqueous solution the N3. radical is found to oxidize aromatic systems such as aniline and phenoxide ions and their deivatives at rate constants of (3-5) X 109 M-1s-1.In contrast to the reactions of OH radicals, wh
