Check Digit Verification of cas no

The CAS Registry Mumber 32359-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,3,5 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 32359-20:
(7*3)+(6*2)+(5*3)+(4*5)+(3*9)+(2*2)+(1*0)=99
99 % 10 = 9
So 32359-20-9 is a valid CAS Registry Number.

supporting information, p. 1156 - 1159 (2017/03/14)

The hydroxylated cyclohexenone carboxylic acid moiety of xylosmin was synthesized in eight steps from benzoic acid. The key steps in the synthesis involved the enzymatic dihydroxylation of benzoic acid by the whole cell fermentation with Ralstonia eutroph

Chemoenzymatic approach to synthesis of hydroxylated pyrrolidines from benzoic acid

Adams, David R.,Van Kempen, Johannes,Hudlicky, Jason R.,Hudlicky, Tomas

, p. 1255 - 1274 (2016/10/30)

The fermentation of benzoic acid with R. eutrophus B9 provides the corresponding ipso-diol that serves as a convenient homochiral starting material for the synthesis of oxygenated compounds. In this paper we report the conversion of the ipso-diol to a hydroxylated pyrrolidine, which is found as a subunit in biologically active compounds. The key steps involve the enzymatic oxidation of benzoic acid, the subsequent hetero-Diels-Alder cycloaddition, and the oxidative cleavage, reductive cyclization to form the pyrrolizidine. Experimental and spectral data are provided for all new compounds.

SYNTHESIS OF TETRACYCLINES AND ANALOGUES THEREOF

-

Page/Page column 84-85, (2008/06/13)

The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The modular synthesis of tetracyclines and tetracycline analogs described provides an efficient and enantioselective route to a variety of tetracycline analogs and polycyclines previously inaccessible via earlier tetracycline syntheses and semi-synthetic methods. These analogs may be used as anti-microbial agents or anti-proliferative agents in the treatment of diseases of humans or other animals.

1,cis-2-Dihydroxycyclohexa-3,5-diene-1-carboxylic acid, 2, produced by Pseudomonas putide, U103, was shown via X-ray analysis of its p-bromobenzoylmethyl ester to have (1S 2R) absolute stereochemistry.The stereo- and regio-selectivity of a series of cycloadditions of the methyl ester 3 (R = Me) the methyl ester acetonide 5 and the hydroxymethylacetonide 6 (R = H) with singlet oxygen, 4-phenyl-4,5-dihydro-3H-1,2,4-triazole-3,5-dione, N-phenylmaleimide and nitrosobenzene have been established.The stereochemistry of the oxygen adduct 7 of 5 was unambiguously assigned by X-ray analysis of 7.The acetonides 5 and 6 (R = H) were attacked by the dienophiles anti to the acetonide group.The diol ester 3 underwent attack on the face syn to the diol groups.The regiochemistry of the addition of nitrosobenzene was predominantly with the N-phenyl group distal to the ester function in 3 and 5, but proximal to the hydroxymethyl group in 6 (R = H).
