Check Digit Verification of cas no

The CAS Registry Mumber 104808-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,0 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104808-53:
(8*1)+(7*0)+(6*4)+(5*8)+(4*0)+(3*8)+(2*5)+(1*3)=109
109 % 10 = 9
So 104808-53-9 is a valid CAS Registry Number.

Factors Affecting the Regioselection of the Allylic Imidates Iodocyclization

Bongini, Alessandro,Cardillo, Giuliana,Orena, Mario,Sandri, Sergio,Tomasini, Claudia

, p. 4905 - 4910 (1986)

The regiochemistry of thr iodocyclization reaction of allylic imidates leading to 4,5-dihydro-1,3-oxazoles or to 4,5-dihydro-1,3-oxazines strongly depends on the configuration of the double bond: (E)-allylic imidatesafford preferentially 4,5-dihydro-1,3-oxazines through a 6-endo closure, whereas (Z)-allylic imidates afford preferentially 4,5-dihydro-1,3-oxazoles through a 5-exo closure.Furthermore a study on the effect of an oxygen atom vicinal to the double bond is reported.
