459142-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 459142-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,9,1,4 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 459142-81:
(8*4)+(7*5)+(6*9)+(5*1)+(4*4)+(3*2)+(2*8)+(1*1)=165
165 % 10 = 5
So 459142-81-5 is a valid CAS Registry Number.

, p. 1121 - 1123 (2007/10/03)
Reduction of ethanethiol esters of α-amino acids to α-amino aldehydes by triethylsilane and catalytic palladium-on-carbon is described. α-Amino aldehydes with Boc, Cbz, or Fmoc protection could be obtained without racemization in high yield.
