Check Digit Verification of cas no

The CAS Registry Mumber 138769-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,6 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138769-92:
(8*1)+(7*3)+(6*8)+(5*7)+(4*6)+(3*9)+(2*9)+(1*2)=183
183 % 10 = 3
So 138769-92-3 is a valid CAS Registry Number.

Chemoenzymatic Synthesis of Advanced Intermediates for Formal Total Syntheses of Tetrodotoxin

Baidilov, Daler,Rycek, Lukas,Trant, John F.,Froese, Jordan,Murphy, Brennan,Hudlicky, Tomas

, p. 10994 - 10998 (2018/06/04)

Advanced intermediates for the syntheses of tetrodotoxin reported by the groups of Fukuyama, Alonso, and Sato were prepared. Key steps include the toluene dioxygenase mediated dihydroxylation of either iodobenzene or benzyl acetate. The resulting diene diols were transformed into Fukuyama's intermediate in six steps, into Alonso's intermediate in nine steps, and into Sato's intermediate in ten steps.

Enzymatic and chemoenzymatic synthesis and stereochemical assignment of cis-dihydrodiol derivatives of monosubstituted benzenes

Boyd, Derek R.,Sharma, Narain D.,Byrne, Breige,Hand, Mark V.,Malone, John F.,Sheldrake, Gary N.,Blacker, John,Dalton, Howard

, p. 1935 - 1943 (2007/10/03)

Toluene dioxygenase-catalysed oxidation of mono-substituted benzene substrates (R = F, Cl, Br, I, Me, Et, CH2OAc, CH=CH2, C=CH, CF3, CN, OMe, OEt, SMe) in growing cultures of Pseudomonas putida UV4 yielded the corresponding cis-dihydrodiol metabolites. Palladium-catalysed cross-coupling of cis-(1S,2S)-1,2-dihydroxy-3-iodocyclohexa-3,5-diene with a range of tributyltin compounds provided a chemoenzymatic route to a further series of cis-dihydrodiol derivatives of monosubstituted benzenes (R = D, CH2CH=CH2, Bun, SEt, SPr1, SBu1, SPh, SC6H4Me-4). The enantiopurities and absolute configurations of the cis-dihydrodiols, obtained by both enzymatic and chemoenzymatic routes, were determined by several new methods including 1H NMR spectroscopic analysis of the bis-MTPA esters of the 4-phenyl-1,2,4-triazoline-3,5-dione cycloadducts, X-ray crystallography, circular dichroism spectroscopy and stereochemical correlation.

Enzymatic and Chemical Syntheses of cis-Dihydrodiol Derivatives of Monocyclic Arenes

Boyd, Derek R.,Hand, Mark V.,Sharma, Narain D.,Chima, Jagdeep,Dalton, Howard,Sheldrake, Gary N.

, p. 1630 - 1632 (2007/10/02)

Metabolism of bromobenzene and iodobenzene by growing cultures of Pseudomonas putida UV4 gave the corresponding cis-dihydrodiol products 1 and 2 in high yields; subsequent direct chemical substitution of the halogen atoms in these metabolites provided a new range of enantiomerically pure cis-dihydrodiols of known absolute configuration.
