Check Digit Verification of cas no

The CAS Registry Mumber 40568-79-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,6 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40568-79:
(7*4)+(6*0)+(5*5)+(4*6)+(3*8)+(2*7)+(1*9)=124
124 % 10 = 4
So 40568-79-4 is a valid CAS Registry Number.

Kinetic resolution of (±)-diethyl- and dibenzyl hydroxy(phenyl) methanephosphonates and their acyl derivatives with lipases

Malinowska, Barbara,Majewska, Paulina,Szatkowski, Pawel,Kafarski, Pawel,Lejczak, Barbara

, p. 271 - 277 (2012/03/27)

A wide variety of commercially available lipases and microbial whole cells were tested for biotransformations of (±)-diethyl and dibenzyl hydroxyl(phenyl)methanephosphonates. Biocatalytic hydrolysis of acylated hydroxyphosphonates by whole cells of Bacillus subtilis gave optically active compounds with 95%eeS. Enantioselectivities obtained when using commercially available enzymatic preparations were less satisfactory, leading to both compounds with an enantiomeric excess in the range 15-35%. Screening lipases for their ability to acylate these phosphonates or to hydrolyze their acylated derivatives enabled selection of enzymes and organisms suitable for use in both processes.
