Check Digit Verification of cas no
The CAS Registry Mumber 171018-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,0,1 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 171018-94:
(8*1)+(7*7)+(6*1)+(5*0)+(4*1)+(3*8)+(2*9)+(1*4)=113
113 % 10 = 3
So 171018-94-3 is a valid CAS Registry Number.

Enantiospecific synthesis of 5-methoxy-D(+)- or L(-) tryptophan
Zhang,Cook
, p. 3883 - 3900 (1995)
A method for the enantiospecific synthesis of 5-methoxy-D(+)-tryptophan 8 or the L(-)-optical antipode is described. This procedure can be scaled up and performed without the need for extensive chromatographic separations. It provides for the first time t
