Check Digit Verification of cas no
The CAS Registry Mumber 130753-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,5 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 130753-28:
(8*1)+(7*3)+(6*0)+(5*7)+(4*5)+(3*3)+(2*2)+(1*8)=105
105 % 10 = 5
So 130753-28-5 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.
