Check Digit Verification of cas no

The CAS Registry Mumber 189164-67-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,1,6 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189164-67:
(8*1)+(7*8)+(6*9)+(5*1)+(4*6)+(3*4)+(2*6)+(1*7)=178
178 % 10 = 8
So 189164-67-8 is a valid CAS Registry Number.

Hydrocarbon oxidation vs C-C bond-forming approaches for efficient syntheses of oxygenated molecules

Fraunhoffer, Kenneth J.,Bachovchin, Daniel A.,White, M. Christina

, p. 223 - 226 (2007/10/03)

(Chemical Equation Presented) A hydrocarbon oxidation approach has been applied to the construction of several linear (E)-allylic alcohols that have served as intermediates in the synthesis of natural products and natural product-like molecules. In the original syntheses, these intermediates were constructed using a standard Wittig-type olefination approach. We report here that routes to these same intermediates designed around a hydrocarbon oxidation approach are more efficient both in the total number of functional group manipulations (FGMs) and overall steps, as well as in the overall yield.
