349555-97-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 349555-97-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,5,5 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 349555-97:
(8*3)+(7*4)+(6*9)+(5*5)+(4*5)+(3*5)+(2*9)+(1*7)=191
191 % 10 = 1
So 349555-97-1 is a valid CAS Registry Number.

Asymmetric total synthesis of (-)-deoxoprosophylline
Jourdant, Angélique,Zhu, Jieping
, p. 3431 - 3434 (2007/10/03)
Asymmetric syntheses of (-)-deoxoprosophylline from chiral L-N,N-dibenzyl serine (TBDMS) aldehyde is reported. A highly diastereoselective intramolecular reductive amination of ω-oxo amino diol is a key step of the present synthesis.
