Check Digit Verification of cas no

The CAS Registry Mumber 198640-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,6,4 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 198640-87:
(8*1)+(7*9)+(6*8)+(5*6)+(4*4)+(3*0)+(2*8)+(1*7)=188
188 % 10 = 8
So 198640-87-8 is a valid CAS Registry Number.

Stereoselective syntheses of 4-amino-aldoses, and chiral pyrrolidine derivatives from glycosylenamines

Fuentes, Jose,Olano, David,Pradera, M. Angeles

, p. 3443 - 3456 (1997)

The stereocontrolled synthesis of N-protected 4-amino-4-deoxy-D-galacto and -L-arabino-pyranoses starting from glycosylenamines via aza- anhydropyranoses is described. The steroselective transformation of the intermediate aza-anhydropyranoses into chiral pyrrolidines is also reported.
