Check Digit Verification of cas no

The CAS Registry Mumber 18779-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,7 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18779-57:
(7*1)+(6*8)+(5*7)+(4*7)+(3*9)+(2*5)+(1*7)=162
162 % 10 = 2
So 18779-57-2 is a valid CAS Registry Number.

Site-selective benzoin-type cyclization of unsymmetrical dialdoses catalyzed by N-heterocyclic carbenes for divergent cyclitol synthesis

Kang, Bubwoong,Wang, Yinli,Kuwano, Satoru,Yamaoka, Yousuke,Takasu, Kiyosei,Yamada, Ken-Ichi

supporting information, p. 4469 - 4472 (2017/04/26)

A highly site-selective N-heterocyclic carbene (NHC)-catalyzed benzoin-type cyclization of unsymmetrical dialdoses is developed to enable a divergent cyclitol synthesis. The choice of chiral NHCs and protecting groups affects the site-selectivity. The resulting inososes are converted into epi-, muco- and myo-inositols, and their chiral protected derivatives are formed in good yields.

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.
