90355-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90355-93-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,5 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90355-93:
(7*9)+(6*0)+(5*3)+(4*5)+(3*5)+(2*9)+(1*3)=134
134 % 10 = 4
So 90355-93-4 is a valid CAS Registry Number.

Regiospecific N-Monoalkylations of Ditertiary Diamines
Chung, Byung-Ho,Zymalkowski, Felix
, p. 307 - 313 (2007/10/02)
N-Monoalkylations of ditertiary diamines succeed best in nitromethane or ethanol at low temperatures.Unsymmetrical 1,3-diaminopropanes as model compounds react selectively under these conditions at the sterically less hindered nitrogen atom.
