55698-44-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55698-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,9 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55698-44:
(7*5)+(6*5)+(5*6)+(4*9)+(3*8)+(2*4)+(1*4)=167
167 % 10 = 7
So 55698-44-7 is a valid CAS Registry Number.

, p. 1131 - 1134 (2007/10/03)
Halogen addition at the C≡C bond of acetylenic amines was studied. It was found that in nonpolar solvents the halogens did not insert into the multiple bond but form quaternary dihaloammonium salts. At the same time the use of the acetylenic amines as hyd
