69209-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69209-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,2,0 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69209-30:
(7*6)+(6*9)+(5*2)+(4*0)+(3*9)+(2*3)+(1*0)=139
139 % 10 = 9
So 69209-30-9 is a valid CAS Registry Number.

Oxidation during reductive cyclisations using Bu3SnH
Bowman, W. Russell,Heaney, Harry,Jordan, Benjamin M.
, p. 10119 - 10128 (2007/10/02)
Reductive cyclisations using Bu3SnH include an "oxidation" step if the removal of an acidic proton from the intermediate cyclised radical, by Bu3SnH acting as a base, is favourable. A "pseudo" SRN1 mechanism is proposed.
