Check Digit Verification of cas no

The CAS Registry Mumber 126109-42-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,1,0 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126109-42:
(8*1)+(7*2)+(6*6)+(5*1)+(4*0)+(3*9)+(2*4)+(1*2)=100
100 % 10 = 0
So 126109-42-0 is a valid CAS Registry Number.

Synthesis of L-2,3,5,6-tetrafluoro-4-(phosphonomethyl)phenylalanine, a novel non-hydrolyzable phosphotyrosine mimetic and L-4-(phosphonodifluoromethyl)phenylalanine

Liu, Wang-Qing,Roques, Bernard P.,Garbay, Christiane

, p. 1389 - 1392 (1997)

A new non-hydrolyzable phosphotyrosine analogue, L-F4Pmp and its N-Fmoc protected derivative were prepared by using an enantioselective synthetic pathway with camphor sultam as chiral auxiliary. The side chain pKa2 (6.9) of L-F4

Biotransformation of new racemic (R,S)-5-benzylhydantoin derivatives by D-hydantoinases from adzuki bean

Latacz, Gniewomir,Kie?-Kononowicz, Katarzyna

, p. 117 - 124 (2014/04/17)

In the present work the scope of D-hydantoinase enzyme application was increased towards new racemic (R,S)-5-benzylhydantoin derivatives. Five new substrates for the D-hydantoinase (R,S)-5-(3′-carboxybenzyl)hydantoin, (R,S)-5-(4′-carboxybenzyl)hydantoin, (R,S)-5-(2′-carbomethoxybenzyl) hydantoin, (R,S)-5-(3′-carbomethoxybenzyl)hydantoin and (R,S)-5-(4′(4-ethoxycarboxy)propoxybenzyl)hydantoin were synthesised and converted using a two-step hydantoinase process into their corresponding D-phenylalanine derivatives. In this study two D-hydantoinases from Vigna angularis (adzuki bean) obtained from commercial sources were used: pure, isolated directly from Vigna angularis (V.a.D-HYD) 494 U/g and immobilised, recombinant, cloned and expressed in Escherichia coli (rD-HYD) 53.1 U/g. The results obtained showed that the examined enzymes catalysed hydrolysis of all new substrates into their corresponding N-carbamoyl-D-phenylalanine derivatives. High enantiomeric purities of the resulting D-phenylalanine derivatives were also determined. However, very low conversion yields of (R,S)-5-(3′- carboxybenzyl)hydantoin and (R,S)-5-(2′-carbomethoxybenzyl)hydantoin to corresponding N-carbamoyl-D amino acid were observed. Three D-phenylalanine derivatives: 4-carboxy-D-phenylalanine, 3-carbomethoxy-D-phenylalanine and 4-carbopropoxy-D-phenylalanine were obtained and isolated from the reaction mixtures using ion-exchange chromatography.
