269727-55-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 269727-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,7,2 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 269727-55:
(8*2)+(7*6)+(6*9)+(5*7)+(4*2)+(3*7)+(2*5)+(1*5)=191
191 % 10 = 1
So 269727-55-1 is a valid CAS Registry Number.

Synthesis and reactivity of ephedrine alkaloid derivatives of aminoacetic acid hydrazide
Nurkenov,Kulakov,Gazaliev
, p. 1669 - 1672 (2007/10/03)
Hydrazides of N-l-ephedrinyl- and N-d-pseudoephedrinylacetic acids were prepared by hydrazinolysis of the corresponding morpholones. The products were acylated with certain acid chlorides and condensed with acetoacetic ester and acetylacetone.
