140202-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140202-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,2,0 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140202-28:
(8*1)+(7*4)+(6*0)+(5*2)+(4*0)+(3*2)+(2*2)+(1*8)=64
64 % 10 = 4
So 140202-28-4 is a valid CAS Registry Number.

Resolution of N-protected amino acid esters using whole cells of Candida parapsilosis ATCC 7330
Stella, Selvaraj,Chadha, Anju
experimental part, p. 457 - 460 (2010/06/21)
Whole cells of Candida parapsilosis ATCC 7330 were used for the resolution of N-acetyl amino acid esters. Excellent enantioselectivities (E = 40 to >500) were achieved for the resolution of N-protected protein and non-protein amino acid esters giving good yields (28-50%) and high enantiomeric excesses (up to >99%) for both enantiomers.
