Check Digit Verification of cas no
The CAS Registry Mumber 774611-13-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,4,6,1 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 774611-13:
(8*7)+(7*7)+(6*4)+(5*6)+(4*1)+(3*1)+(2*1)+(1*3)=171
171 % 10 = 1
So 774611-13-1 is a valid CAS Registry Number.

Asymmetric synthesis of (-)-swainsonine
Lindsay, Karl B.,Pyne, Stephen G.
, p. 669 - 672 (2007/10/03)
This paper describes a new synthesis of (-)-swainsonine via the ring-closing metathesis reaction of a substituted 3-allyl-4-vinyloxazolindin-2- one and subsequent diastereoselective syn-dihydroxylation of the resulting pyrrolo[1,2-c]oxazol-3-one.
