1264175-90-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1264175-90-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,4,1,7 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1264175-90:
(9*1)+(8*2)+(7*6)+(6*4)+(5*1)+(4*7)+(3*5)+(2*9)+(1*0)=157
157 % 10 = 7
So 1264175-90-7 is a valid CAS Registry Number.

18O assisted analysis of a γ,δ-epoxyketone cyclization: Synthesis of the C16-C28 fragment of ammocidin D
Chau, Stephen T.,Hayakawa, Yoichi,Sulikowski, Gary A.
, p. 756 - 759 (2011/04/24)
The C16-C28 fragment common to the cytotoxic macrolide ammocidin D has been prepared by a stereospecific 5-exo closure of a γ,δ-epoxyketone followed by a rearrangement to a pyran acetal. The reaction pathway was traced by 18O labeling of the ke
