Check Digit Verification of cas no

The CAS Registry Mumber 78012-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,1 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78012-18:
(7*7)+(6*8)+(5*0)+(4*1)+(3*2)+(2*1)+(1*8)=117
117 % 10 = 7
So 78012-18-7 is a valid CAS Registry Number.

Structure and Synthesis of Pallescensin E Utilising a Modified Wadsworth-Emmons Reaction

Baker, Raymond,Sims, Russell

, p. 3087 - 3091 (2007/10/02)

A modified Wadsworth-Emmons reaction using a catalytic amount of 15-crown-5 has been employed in the synthesis of the naturally occurring furosesquiterpene pallescensin E.The structure of this compound has been confirmed by comparison of its spectral data with those of the synthesised isomer, 9,10-dihydro-7,8-dimethyl-4H-benzocycloheptafuran.
