Check Digit Verification of cas no

The CAS Registry Mumber 1023310-53-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,3,1 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1023310-53:
(9*1)+(8*0)+(7*2)+(6*3)+(5*3)+(4*1)+(3*0)+(2*5)+(1*3)=73
73 % 10 = 3
So 1023310-53-3 is a valid CAS Registry Number.

Synthesis of allo - And epi -inositol via the NHC-catalyzed carbocyclization of carbohydrate-derived dialdehydes

Stockton, Kieran P.,Greatrex, Ben W.,Taylor, Dennis K.

, p. 5088 - 5096 (2014/06/23)

A synthesis of carbocyclic sugars from carbohydrate-derived dialdehydes using organocatalysis has been developed. Sorbitol, mannitol, and galactitol were converted via 1,6-tritylation, perbenzylation or permethylation, detritylation, and Swern oxidation into 2,3,4,5-tetra-O-alkyl-dialdoses that were cyclized via the benzoin reaction promoted by a triazolium carbene. Manno- and galacto-configured dialdehydes gave predominantly single inosose stereoisomers in up to 75% yield if the mixture was acetylated prior to isolation while the gluco-dialdehyde afforded a mixture of three stereoisomers in 61% overall yield. The inososes were stereospecifically reduced using sodium borohydride and then deprotected to give allo- and epi-inositol in good yield that confirmed the structural and stereochemical assignments.

A straightforward synthesis of perbenzylated conduritols from alditols by ring closing olefin metathesis

Gallos, John K.,Koftis, Theocharis V.,Sarli, Vassiliki C.,Litinas, Konstantinos E.

, p. 3075 - 3077 (2007/10/03)

The synthesis of perbenzylated conduritols A, E and F has been achieved in six steps by formal conversion of galactitol, D-mannitol and D-glucitol into the respective terminal dienes, followed by ring closing olefin metathesis. The Royal Society of Chemistry 1999.
