403984-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 403984-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,9,8 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 403984-50:
(8*4)+(7*0)+(6*3)+(5*9)+(4*8)+(3*4)+(2*5)+(1*0)=149
149 % 10 = 9
So 403984-50-9 is a valid CAS Registry Number.

Novel asymmetric total synthesis of the natural (+)-6-epicastanospermine
Zhang, Hong-Xing,Xia, Peng,Zhou, Wei-Shan
, p. 2015 - 2020 (2007/10/03)
An efficient noncarbohydrate-based enantioselective synthesis of (+)-6-epicastanospermine has been developed utilizing the Sharpless asymmetric aminohydroxylation of furyl acrylate and oxidation of α-furfurylamine derivative 17 as key steps.
