19030-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19030-85-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,3 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19030-85:
(7*1)+(6*9)+(5*0)+(4*3)+(3*0)+(2*8)+(1*5)=94
94 % 10 = 4
So 19030-85-4 is a valid CAS Registry Number.

CsOH-promoted chemoselective mono-N-alkylation of diamines and polyamines
Salvatore,Schmidt,Shin,Nagle,Worrell,Jung
, p. 9705 - 9708 (2000)
Selective N-alkylation of diamines and polyamines was carried out using cesium hydroxide, 4 ? molecular sieves, and DMF. This protocol was highly chemoselective, favoring mono-N-alkylation over overalkylations. (C) 2000 Published by Elsevier Science Ltd.
