1373344-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1373344-34-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,3,4 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1373344-34:
(9*1)+(8*3)+(7*7)+(6*3)+(5*3)+(4*4)+(3*4)+(2*3)+(1*4)=153
153 % 10 = 3
So 1373344-34-3 is a valid CAS Registry Number.

Enantioselective synthesis of a taxol C ring
Ma, Cong,Schiltz, Stephanie,Prunet, Joelle
, p. 1579 - 1594 (2012/05/19)
An enantioselective synthesis of a C ring of taxol has been accomplished. The key step is an oxidative cleavage of a derivative of the Wieland-Miescher ketone. A first attempt of a Shapiro reaction modelling the coupling of the C ring with the A fragment of taxol was also successful.
