117954-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117954-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,5 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117954-74:
(8*1)+(7*1)+(6*7)+(5*9)+(4*5)+(3*4)+(2*7)+(1*4)=152
152 % 10 = 2
So 117954-74-2 is a valid CAS Registry Number.

Demopoulos, Vassilis J.
, p. 635 - 638 (2007/10/02)
3-(2-Di-n-propylaminoethyl)pyrrole (1a) was prepared in good yield by reduction of pyrrole-3-(N,N-di-n-propylglyoxyamide) (9) with lithium aluminum hydride. 3-(2-Di-n-propylaminoethyl)-5-acetylpyrrole (1b) was prepared by first acetylation of 1-p-toluenes
