Check Digit Verification of cas no

The CAS Registry Mumber 198565-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,5,6 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 198565-90:
(8*1)+(7*9)+(6*8)+(5*5)+(4*6)+(3*5)+(2*9)+(1*0)=201
201 % 10 = 1
So 198565-90-1 is a valid CAS Registry Number.

A short synthesis of azasugars via aldol reaction of chelated amino acid ester enolates

Grandel, Roland,Kazmaier, Uli

, p. 8009 - 8012 (2007/10/03)

Aldol reactions of chelated amino acid ester enolates with chiral aldehydes gives rise to polyhydroxylated amino acids in a highly stereoselective fashion. These oxygenated amino acids can be converted into polyhydroxylated pipecolinic acids and azasugars by cyclization using the Mitsunobu reaction. A interesting epimerization was observed during the cyclization.
