Check Digit Verification of cas no

The CAS Registry Mumber 92591-97-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,5,9 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 92591-97:
(7*9)+(6*2)+(5*5)+(4*9)+(3*1)+(2*9)+(1*7)=164
164 % 10 = 4
So 92591-97-4 is a valid CAS Registry Number.

Enantiospecific Synthesis of Shikimic Acid from D-Mannose: Formation of a Chiral Cyclohexene by Intramolecular Olefination of a Carbohydrate-derived Intermediate

Fleet, George W. J.,Shing, Tony K. M.,Warr, Steven M.

, p. 905 - 908 (2007/10/02)

An enantiospecific synthesis of (-)-shikimic acid from D-mannose in an overall yield of 39percent is described, in which the key step is an intramolecular Wadsworth-Emmons olefination reaction of a phosphonate.Nucleophilic displacement of triflate from benzyl 2,3-O-isopropylidene-5-O-trifluoromethylsulphonyl-α-D-lyxofuranoside by the sodium salt of t-butyl dimethoxyphosphorylacetate provides a rare example of substitution at the C-5 position of a furanose derivative by a carbanion.
