142820-48-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142820-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,2 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 142820-48:
(8*1)+(7*4)+(6*2)+(5*8)+(4*2)+(3*0)+(2*4)+(1*8)=112
112 % 10 = 2
So 142820-48-2 is a valid CAS Registry Number.

Transesterification-based enzymatic resolutions of racemic 3-hydroxy-4-pentenylurethanes in organic solvents
Takahata,Uchida,Momose
, p. 3331 - 3332 (2007/10/02)
An expedient synthesis of homochiral N-protected (R)- and (S)-3-hydroxy-4-pentenylamines (1 and 2) has been accomplished via the enzymatic resolution of the racemic 1 and 2 mediated by immobilized lipase in pentane.
