Check Digit Verification of cas no

The CAS Registry Mumber 179052-82-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,0,5 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 179052-82:
(8*1)+(7*7)+(6*9)+(5*0)+(4*5)+(3*2)+(2*8)+(1*2)=155
155 % 10 = 5
So 179052-82-5 is a valid CAS Registry Number.

Kinetic resolution of 2-acylated-1,2-diols by lipase-catalyzed enantiomer selective acylation

Egri, Gabriella,Baitz-Gacs, Eszter,Poppe, Laszlo

, p. 1437 - 1448 (2007/10/03)

Enantiomer selectivity of lipase catalyzed acylation of 2-acylated 1,2-diols was studied. First, acylation of 2-acetoxyheptan-1-ol rac-3b with vinyl acetate was investigated by varying the enzymes and the solvent, showing the highest enantiomer selectivity by using lipase from Pseudomonas fluorescens (PfL) in hexane-vinyl acetate (VA). We have found varying or even reversed enantiomer selectivity for different secondary acyl moieties in 2-acyloxyheptan-1-ols rac-3bA-F. Next, all six possible types of enantiomer selective biotransformations (hydrolysis of diacetate and the two kinds of monoacetetes; acylation of diol and the two kinds of monoacetates) were compared on two model diols rac-4b,d. Among the transformations investigated, acetylation of secondary monoacetates rac-3b,d showed the highest enantiomer selectivity. Finally, PfL catalyzed acetylations of several 2-acetylated 1,2-diols rac-3a-g were investigated under our optimum conditions.
