Check Digit Verification of cas no

The CAS Registry Mumber 109857-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,5 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109857-34:
(8*1)+(7*0)+(6*9)+(5*8)+(4*5)+(3*7)+(2*3)+(1*4)=153
153 % 10 = 3
So 109857-34-3 is a valid CAS Registry Number.

Regio- and diastereoselection in the oxaziridinium salt oxidation of acyclic allylic acetates

Poisson, David,Cure, Gilles,Solladié, Guy,Hanquet, Gilles

, p. 3745 - 3748 (2007/10/03)

Oxaziridinium salt 1 is a versatile oxygen transfer agent towards olefins. An important threo selectivity is observed with acyclic allylic acetates due to 1,3-allylic strain (A1,3). The π-facial selectivity in the epoxide formation is interpretated as a consequence of an interaction between the residual positive charge on nitrogen and the neighbouring acetate in the transition state. Such an interaction is not strong enough to balance the lowered nucleophilicity of the 2,3 double bond in the geraniol acetate 3a.
