250583-06-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 250583-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,5,8 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 250583-06:
(8*2)+(7*5)+(6*0)+(5*5)+(4*8)+(3*3)+(2*0)+(1*6)=123
123 % 10 = 3
So 250583-06-3 is a valid CAS Registry Number.

Preparation of endothelin antagonist ABT-627
Wittenberger, Steven J.,McLaughlin, Maureen A.
, p. 7175 - 7178 (2007/10/03)
An enantioselective synthesis of ABT-627 is described. The key transformation is a diastereoselective 6-endo-trig cyclization to produce a 3,4,5-trisubstituted-1,2-oxazine which is ring contracted to the 2,3,4-tri-substituted-pyrrolidine core of ABT-627.
