Check Digit Verification of cas no
The CAS Registry Mumber 20277-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,7 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20277-92:
(7*2)+(6*0)+(5*2)+(4*7)+(3*7)+(2*9)+(1*2)=93
93 % 10 = 3
So 20277-92-3 is a valid CAS Registry Number.

Process for isolating diarylguanidines
-
, (2008/06/13)
Diarylguanidines can be isolated from the crude melt from the reaction of arylamines and cyanogen chloride in excellent quality and yield by dissolving the hot melt in water, extracting this solution with at least one polar, water-insoluble, organic compound, and precipitating from the purified aqueous solution the diarylguanidine by adding alkali metal hydroxide.
