1123921-69-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1123921-69-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,3,9,2 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1123921-69:
(9*1)+(8*1)+(7*2)+(6*3)+(5*9)+(4*2)+(3*1)+(2*6)+(1*9)=126
126 % 10 = 6
So 1123921-69-6 is a valid CAS Registry Number.

A new synthetic route to functionalized 9,10-diarylanthracenes has been developed. 9,10-Epoxyanthracene intermediates were prepared by [4+2] cycloaddition of 1,3-diarylisobenzofuran with a variety of functionalized benzyne intermediates, which were obtained by Mg(TMP) 2 ·2LiCl-mediated benzyne generation. For the cleavage of the resultant 9,10-epoxyanthracene intermediates, we developed mild deoxygenation conditions using a combination of trifluoroacetic acid and Et 3 SiH. The utility of this sequence was demonstrated by application to the synthesis of 5,7,12,14-tetraphenylpentacene.
