Check Digit Verification of cas no

The CAS Registry Mumber 98092-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,9 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98092-68:
(7*9)+(6*8)+(5*0)+(4*9)+(3*2)+(2*6)+(1*8)=173
173 % 10 = 3
So 98092-68-3 is a valid CAS Registry Number.

SYNTHESES OF METHYL 6-DEOXY-6-HYDROXYAMINO-α-D-GLUCOPYRANOSIDE, 6'-N-HYDROXYKANAMYCIN A, AND 6'-N-HYDROXYDIBEKACIN

, p. 195 - 206 (2007/10/02)

Methyl-6-deoxy-6-hydroxyamino-α-D-glucopyranoside has been prepared from methyl 6-amino-6-deoxy-α-D-glucopyranoside via oxidation with hydrogen peroxide in the presence of sodium tungstate , followed by reduction with sodium cyanoborohydride in an acidic medium.Acetylation of the Z isomer of 2 gave a nitrile derivative.The above oxidation-reduction procedure was applied to kanamycin A and dibekacin, starting from the corresponding 6'-amino-N-tosyl derivatives.On treatment with sodium in liquid ammonia, 6'-deamino-6'-hydroxyimino-1,3,3''-tri-N-tosylkanamycin A gave the corresponding N-detosyl derivative in good yield with the 6'-aldoxime group remaining intact, but, with 6'-deamino-6'-hydroxyimino-1,3,2',3''-tetra-N-tosyldibekacin, the N-detosyl derivative (17) was obtained only by a very short reaction period.The antibacterial activities of 17 and 6'-N-hydroxydibekacin were demonstrated.
