Check Digit Verification of cas no

The CAS Registry Mumber 80312-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,1 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80312-57:
(7*8)+(6*0)+(5*3)+(4*1)+(3*2)+(2*5)+(1*7)=98
98 % 10 = 8
So 80312-57-8 is a valid CAS Registry Number.

STEREOSELEKTIVE SYNTHESE VON α-GLUCOSIDEN MIT 1,1'-DIACETAL-STRUKTUR

Tietze, Lutz-F.,Fischer, Roland

, p. 3239 - 3242 (1981)

Reaction of (1b) and (1d) with the acetal (2a) in presence of trimethylsilyl trifluoromethanesulfonate at -70 deg C gives the α-glucosides (3a) and (4a), whereas (1a) and (1c) lead to the β-glucosides (4c) and (4b).At 0 deg C reaction of (1a) with the acetals (2b-g) gives exclusively the α-glucosides (3b-g).
