Check Digit Verification of cas no
The CAS Registry Mumber 20669-05-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,6 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20669-05:
(7*2)+(6*0)+(5*6)+(4*6)+(3*9)+(2*0)+(1*5)=100
100 % 10 = 0
So 20669-05-0 is a valid CAS Registry Number.

The condensation of a Grignard reagents with hindered acid chlorides in THF at low temperature, yields ketones which are generally difficult to obtain and avoids the side reaction caused with a CuCl catalyst.Applied to unsaturated Grignard reagents and acid chlorides, this method also yields unsaturated ketones, such as the Artemisia ketone.
