557789-96-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 557789-96-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,7,8 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 557789-96:
(8*5)+(7*5)+(6*7)+(5*7)+(4*8)+(3*9)+(2*9)+(1*6)=235
235 % 10 = 5
So 557789-96-5 is a valid CAS Registry Number.

Semisynthesis of 3′(2′)-O-(aminoacyl)-tRNA derivatives as ribosomal substrate
Cui, Zhiyong,Zhang, Biliang
, p. 297 - 310 (2008/02/08)
An efficient synthesis of (3′-terminally) 3′(2′)-O- aminoacylated pCpA derivatives is described, which could lead to the production of (aminoacyl)-tRNAs following T4 RNA ligase mediated ligation. The tetrahydrofuranyl (thf) group was used as a permanent p
