121203-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121203-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,0 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121203-05:
(8*1)+(7*2)+(6*1)+(5*2)+(4*0)+(3*3)+(2*0)+(1*5)=52
52 % 10 = 2
So 121203-05-2 is a valid CAS Registry Number.

Novel 3-O-α-L-Cladinosyl Sixteen-membered Macrolide Antibacterials
Mallams, Alan K.,Rossman, Randall R.
, p. 799 - 805 (2007/10/02)
A novel series of 3-O-α-L-cladinosyl sixteen-membered macrolide antibacterials has been synthesized by glycosidation of the 3-hydroxy group of 12,13-de-epoxy-12,13-didehydrorosaramicin, 12,13-de-epoxy-12,13-didehydro-20-deoxorosaramicin, desmycosin, 20-de
