Check Digit Verification of cas no
The CAS Registry Mumber 477953-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,9,5 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 477953-53:
(8*4)+(7*7)+(6*7)+(5*9)+(4*5)+(3*3)+(2*5)+(1*3)=210
210 % 10 = 0
So 477953-53-0 is a valid CAS Registry Number.

Silicon tether-aided coupling metathesis: Application to the synthesis of attenol A
Van De Weghe, Pierre,Aoun, Darina,Boiteau, Jean-Guy,Eustache, Jacques
, p. 4105 - 4108 (2007/10/03)
(matrixpresented) A new synthesis of attenol A is described. Key features of this work include a crucial silicon tether-aided coupling metathesis step and the use of iodoetherification as an efficient protection method for 1,5-ene-ols.
