821788-48-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 821788-48-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,1,7,8 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 821788-48:
(8*8)+(7*2)+(6*1)+(5*7)+(4*8)+(3*8)+(2*4)+(1*8)=191
191 % 10 = 1
So 821788-48-1 is a valid CAS Registry Number.

Enzymatic desymmetrization of meso-1α,4α-dihydroxy-cis-decalins

Chenevert, Robert,Courchesne, Gabriel,Jacques, Frederic

, p. 3587 - 3590 (2007/10/03)

The stereoselective acetylation of meso-decalindiols 1 and 2 by vinyl acetate in the presence of Candida antarctica lipase gave monoester (1R,4S,4aR,8aS)-5 and (1R,4S,4aR,8aS)-6 in high enantiomeric excess (ee ≥98%). The hydrolysis of the corresponding meso-diacetates 3 and 4 in the presence of porcine liver esterase in phosphate buffer provided the opposite enantiomers.

Enantioselective α-deprotonation-rearrangement of meso-epoxides

Hodgson, David M.,Lee, Gary P.

, p. 1015 - 1016 (2007/10/03)

Enantioselective α-deprotonation-rearrangement of medium-sized (8-, 9- and 10-membered) cycloalkene-derived meso-epoxides using organolithiums in the presence of (-)-sparteine gives bicyclic alcohols in good yields and ees.
