Check Digit Verification of cas no

The CAS Registry Mumber 78147-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,4 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78147-99:
(7*7)+(6*8)+(5*1)+(4*4)+(3*7)+(2*9)+(1*9)=166
166 % 10 = 6
So 78147-99-6 is a valid CAS Registry Number.

Dihydroxylation of polyenes using Narasaka's modification of the upjohn procedure

Gypser, Andreas,Michel, Dominique,Nirschl, David S.,Barry Sharpless

, p. 7322 - 7327 (2007/10/03)

Dihydroxylation of a variety of commercially available polyenes has been investigated using phenylboronic acid, .ZV-methylmorpholine Af-oxide (NMO), and osmium tetroxide in anhydrous solvent. The diastereoselectivity of multiple oxidation steps is in some cases affected by the in situ protection of the intermediate ene-diols as phenyboronic esters, affording polyols not available from the standard Upjohn dihydroxylation procedure. A convenient oxidative deprotection of the phenylboronic esters is also described.

Catalytic One-Pot Osmylation of Cyclohexadienes: Stereochemical and Conformational Studies of the Resulting Polyols

Tschamber, Theophile,Backenstrass, Frederique,Fritz, Hans,Streith, Jacques

, p. 1052 - 1060 (2007/10/02)

Catalytic double osmylation is described for a series of cyclohexadienes in acetone/H2O in the presence of the co-oxidant N-methylmorpholine N-oxide (NMO).The formation of polyols occurred stereospecifically with cyclohexadienes 3, 7, and 11a, leading thereby to tetrols 5a, and 9a and to allo-inositol (14a), respectively.To the contrary, trans-cyclohexadiene-diol 15a gave a mixture of the stereoisomeric inositols 18a (epi), 19a (neo), and 20a (chiro).High-field NMR let to clearcut conformational analyses of the polyhydroxylated derivatives.

A New and Stereospecific Synthesis of Cyclitols: (1,2,4/3)-, (1,2/3,4)-, and (1,3/2,4)-Cyclohexanetetrols

Akbulut, Nihat,Balci, Metin

, p. 3338 - 3342 (2007/10/02)

A new and stereospecific synthesis of (1,2,4/3)-, (1,2/3,4)-, and (1,3/2,4)-cyclohexanetetrols 3a, 4a, and 6a is described.Syn and anti epoxy endoperoxides 9 and 10 were synthesized by epoxidation of endoperoxide 8 with m-chloroperbenzoic acid.Catalytic r
