78094-44-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78094-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,9 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 78094-44:
(7*7)+(6*8)+(5*0)+(4*9)+(3*4)+(2*4)+(1*4)=157
157 % 10 = 7
So 78094-44-7 is a valid CAS Registry Number.

Parker, Kathlyn A.,Petraitis, Joseph J.
, p. 397 - 400 (2007/10/02)
Naphthoquinone 1, a fully functionalized model for intermediates in ansamycin synthesis, was prepared by the intramolecular Claisen condensation of benzofuran 9 followed by oxidation of the novel tricyclic compound 10.
