14598-91-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14598-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,5,9 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14598-91:
(7*1)+(6*4)+(5*5)+(4*9)+(3*8)+(2*9)+(1*1)=135
135 % 10 = 5
So 14598-91-5 is a valid CAS Registry Number.

Resolution of non-proteinogenic amino acids via microbial lipase-catalyzed enantioselective transesterification

Miyazawa, Toshifumi,Mio, Motoe,Watanabe, Yuko,Yamada, Takashi

, p. 219 - 224 (2008/09/20)

A number of non-proteinogenic amino acids bearing aliphatic side chains were resolved with moderate to good enantioselectivities (E = 15-42) through the Burkholderia cepacia lipase-catalyzed enantioselective transesterification of the 2,2,2-trifluoroethyl esters of their N-benzyloxycarbonyl derivatives with methanol as a nucleophile in diisopropyl ether.
