21307-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21307-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,0 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21307-20:
(7*2)+(6*1)+(5*3)+(4*0)+(3*7)+(2*2)+(1*0)=60
60 % 10 = 0
So 21307-20-0 is a valid CAS Registry Number.

Nucleophilic substances for detoxification of phosphorus esters. Surface-active compounds
Reiner,Rossmann
, p. 223 - 231 (1982)
A series of N-substituted hydroxylamine derivatives was synthesized as a potential substitute for calcium hypochlorite. Like calcium hypochlorite, these compounds are highly P(V)-nucleophilic with respect to toxic phosphorus esters. Incorporating surface-
