127862-68-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127862-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,6 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127862-68:
(8*1)+(7*2)+(6*7)+(5*8)+(4*6)+(3*2)+(2*6)+(1*8)=154
154 % 10 = 4
So 127862-68-4 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.
