1252581-02-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1252581-02-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,5,8 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1252581-02:
(9*1)+(8*2)+(7*5)+(6*2)+(5*5)+(4*8)+(3*1)+(2*0)+(1*2)=134
134 % 10 = 4
So 1252581-02-4 is a valid CAS Registry Number.

, p. 7408 - 7411 (2010)
Some bicyclic C-fused chlorinated tetrahydrofuro[3,2-c]azetidin-2-ones were prepared by a fairly general route involving Staudinger reaction of allylic/propargylic imidates with dichloroketene followed by highly diastereoselective CuCl/PMDETA-catalyzed 5-
