473906-82-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 473906-82-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,9,0 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 473906-82:
(8*4)+(7*7)+(6*3)+(5*9)+(4*0)+(3*6)+(2*8)+(1*2)=180
180 % 10 = 0
So 473906-82-0 is a valid CAS Registry Number.

Efficient stereoselective synthesis of enantiopure 2-substituted paraconic acids
Kim, Hyun-Chul,Park, Oee-Sook
, p. 896 - 899 (2008)
Eight enantiopure (2S,3S)-2-aryl-5-oxotetrahydrofuran-3-carboxylic acids have been synthesized. The key step was a highly stereoselective aldol reaction between an N-acyl oxazolidinone and a corresponding aldehyde.
