Check Digit Verification of cas no

The CAS Registry Mumber 7690-75-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,9 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7690-75:
(6*7)+(5*6)+(4*9)+(3*0)+(2*7)+(1*5)=127
127 % 10 = 7
So 7690-75-7 is a valid CAS Registry Number.

Total Synthesis of Linear Polyprenoids. 2. Improved preparation of the Aromatic Nucleus of Ubiquinone

Keinan, Ehud,Eren, Doron

, p. 3872 - 3875 (2007/10/02)

Highly efficient copper-catalyzed polymethoxylation of tribromocresol is the key process in a three-step, practical approach to obtain ubiquinone 0 from p-cresol.Short syntheses of several ubiquinones were achieved via direct, copper-mediated coupling of 2-lithio-3,4,5,6-tetramethoxytoluene to the appropriate polyprenyl bromide.
