133030-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133030-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133030-20:
(8*1)+(7*3)+(6*3)+(5*0)+(4*3)+(3*0)+(2*2)+(1*0)=63
63 % 10 = 3
So 133030-20-3 is a valid CAS Registry Number.

Synthetic applications of Gilman reagents derived from 2-bromo-2-cycloalken-1-one ethylene ketals
Majetich,Leigh,Condon
, p. 605 - 608 (2007/10/02)
Gilman reagents derived from 2-bromo-2-cycloalken-1-one ethylene ketals react with allylic, propargylic or benzylic halides to produce functionalized 1,4-dienes while reaction with Michael acceptors gives 1,4-adducts.
