119904-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119904-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,0 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119904-03:
(8*1)+(7*1)+(6*9)+(5*9)+(4*0)+(3*4)+(2*0)+(1*3)=129
129 % 10 = 9
So 119904-03-9 is a valid CAS Registry Number.

Synthesis and Structure-Activity Relationships of New 9-N-Alkyl Derivatives of 9(S)-Erythromycylamine
Kirst, Herbert A.,Wind, Julie A.,Leeds, James P.,Willard, Kevin E.,Debono, Manuel,et al.
, p. 3086 - 3094 (2007/10/02)
A series of new 9-N-alkyl derivatives of 9(S)-erythromycylamine has been synthesized by reductive alkylation of erythromycylamine with aliphatic aldehydes and sodium cyanoborohydride.Alternative syntheses employing hydrogenation methods have also been dev
