118663-74-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118663-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,6 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 118663-74:
(8*1)+(7*1)+(6*8)+(5*6)+(4*6)+(3*3)+(2*7)+(1*4)=144
144 % 10 = 4
So 118663-74-4 is a valid CAS Registry Number.

Acetylation of secondary hydroxy groups of α- and β-cyclodextrines silyl derivatives

Grachev,Edunov,Kurochkina,Levina,Nifant'ev

, p. 322 - 329 (2011)

The application of acetyl chloride in the combination with different solvents and bases permitted the preparation of silyl derivatives of α- and β-cyclodextrines containing a definite amount of acetyl substituents on the secondary hydroxy groups. It was found that by means of the 1H and 13C NMR spectroscopy it is possible to make an exact attribution of acetyl groups to C2 or C3 carbon atoms of carbohydrate fragments of α- and β-cyclodextrines. Desilylation with ammonium fluoride in methanol gives acetyl derivatives of cyclodextrines containing free primary hydroxy groups.
