736140-57-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 736140-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,6,1,4 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 736140-57:
(8*7)+(7*3)+(6*6)+(5*1)+(4*4)+(3*0)+(2*5)+(1*7)=151
151 % 10 = 1
So 736140-57-1 is a valid CAS Registry Number.

Asymmetric synthesis of (+)-1-epiaustraline and attempted synthesis of australine
Tang, Minyan,Pyne, Stephen G.
, p. 5759 - 5767 (2007/10/03)
A diastereoselective synthesis of the pyrrolizidine alkaloid, (+)-1-epiaustraline has been achieved via a diastereoselective syn-dihydroxylation of a pyrrolo[1,2-c]oxazol-3-one precursor that was readily prepared by a RCM reaction. Attempts to extend this
