Check Digit Verification of cas no

The CAS Registry Mumber 270922-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,0,9,2 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 270922-91:
(8*2)+(7*7)+(6*0)+(5*9)+(4*2)+(3*2)+(2*9)+(1*1)=143
143 % 10 = 3
So 270922-91-3 is a valid CAS Registry Number.

Convergent syntheses of C(1→3)-linked disaccharides starting from isolevoglucosenone

Zhu, Yao-Hua,Demange, Raynald,Vogel, Pierre

, p. 263 - 282 (2000)

Nucleophilic addition (Nu-M+) to isolevoglucosenone 1 generates enolates stereospecifically (exo face addition) that can be reacted with sugar-derived aldehydes to give C(1→3)-linked disaccharide precursors with high diastereoselectivity. Limitations of the method arising from unfavorable aldolate stability can be overcome by using Et2AlI as the nucleophile. This leads to products of Baylis-Hillmann condensations. One example is presented and has led to the preparation of 2,3-anhydro-3-C-[(1S)-2,6-anhydro-D-glycero-D-gulo-heptitol-1-C-yl]-β-D-gulo-pyranose 5. Copyright (C) 2000 Elsevier Science Ltd.
