Check Digit Verification of cas no

The CAS Registry Mumber 138481-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,8 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138481-57:
(8*1)+(7*3)+(6*8)+(5*4)+(4*8)+(3*1)+(2*5)+(1*7)=149
149 % 10 = 9
So 138481-57-9 is a valid CAS Registry Number.

A Route to Several Stereoisomers of Castanospermine

Burgess, Kevin,Chaplin, David A.,Henderson, Ian,Pan, Y. T.,Elbein, Alan D.

, p. 1103 - 1109 (2007/10/02)

The following three stereoisomers of castanospermine have been prepared: (1R,6R,7R,8S,8aR)-1,6,7,8-tetrahydroxyindolizidine (1), (1R,6S,7S,8S,8aR)-1,6,7,8-tetrahydroxyindolizidine (2), and (1R,6R,7S,8S,8aR)-1,6,7,8-tetrahydroxyindolizidine (3).Each of the

Biocatalytic Desymmetrizations of Pentitol Derivatives

Burgess, Kevin,Henderson, Ian

, p. 5701 - 5704 (2007/10/02)

Several acylations of pentitol derivatives mediated by Candida cylindracea have been shown to be enantio-, or diastereo-, group selective; a pattern emerges from the selectivities of these reactions which may have some predictive value.Key words: acylation; catalysis; Candida cylindracea lipase; kinetic amplification of diastereomeric excess
