131966-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131966-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,6 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131966-97:
(8*1)+(7*3)+(6*1)+(5*9)+(4*6)+(3*6)+(2*9)+(1*7)=147
147 % 10 = 7
So 131966-97-7 is a valid CAS Registry Number.

Amino Acid Esters as Chiral Auxiliaries in Barbier-Type Reactions in Aqueous Solution
Waldmann, Herbert
, p. 1317 - 1322 (2007/10/02)
Valine and proline benzyl ester are converted into the aliphatic and aromatic α-oxo amides 5 by activation of the respective α-oxo acid by means of N,N'-diisopropylcarbodiimide.The α-oxo amides 5 undergo Barbier-type reactions with differently substituted
