108946-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108946-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,9,4 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 108946-52:
(8*1)+(7*0)+(6*8)+(5*9)+(4*4)+(3*6)+(2*5)+(1*2)=147
147 % 10 = 7
So 108946-52-7 is a valid CAS Registry Number.

Diels-Alder Reactions of Bissilylated 1,3-Diketones with Azo Dienophiles
Ried, Walter,Reiher, Uwe
, p. 1597 - 1600 (2007/10/02)
The 1,3-bis(tert-butyldimethylsilyloxy)-1,3-butadienes 2a and 2b are obtained by double silylation of the 1,3-diketones 1a and 1b.The dienes 2a and 2b react with various azo dienophiles to yield the Diels-Alder adducts 3a-f.Hydrolysis of these compounds l
