129398-84-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129398-84-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,9 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129398-84:
(8*1)+(7*2)+(6*9)+(5*3)+(4*9)+(3*8)+(2*8)+(1*4)=171
171 % 10 = 1
So 129398-84-1 is a valid CAS Registry Number.

Synthesis and catalytic activities of (S)-1-formylpyrrolidine-2-carboxylic acid derivatives for the enantioselective reductions of both a ketone and a ketimine

Chen, Zhenfei,Zhang, Anjiang,Zhang, Lixue,Zhang, Jing,Lei, Xinxiang

experimental part, p. 266 - 269 (2009/04/10)

A series of (S)-1-formylpyrrolidine-2-carboxylic acid derivatives (6a-t) have been synthesised and examined as chiral organocatalysts in the asymmetric reduction of both ketone 2 and ketimine 3. These organic activators afforded good to moderate enantiose
