13145-22-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13145-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,4 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13145-22:
(7*1)+(6*3)+(5*1)+(4*4)+(3*5)+(2*2)+(1*2)=67
67 % 10 = 7
So 13145-22-7 is a valid CAS Registry Number.

Solvolyses of 2-Deoxy-α- and β-D-Glucopyranosyl 4′-Bromoisoquinolinium Tetrafluoroborates

Zhu, Jiang,Bennet, Andrew J.

, p. 4423 - 4430 (2007/10/03)

The solvolyses of 2-deoxy-α- and β-D-glucopyranosyl 4′-bromoisoquinolinium tetrafluoroborates (1 and 2) were monitored in aqueous methanol, ethanol, trifluoroethanol, and binary mixtures of ethanol and trifluoroethanol. The observed rate constants are consistent with the solvolyses of 1 and 2 proceeding via dissociative (DN * AN) transition states. In comparison to the α-anomer, solvolysis of the β-compound gives a greater transition state charge delocalization onto the ring oxygen atom. Analysis of the solvolysis product ratios indicates that the 2-deoxyglucosyl oxacarbenium ion is not solvent-equilibrated in the solvent mixtures studied. In the solvolysis of compound 1, the solvent trifluoroethanol facilitates diffusional separation of the leaving group and, in so doing, promotes the formation of the retained trifluoroethyl glycoside.
