109351-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109351-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,3,5 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109351-28:
(8*1)+(7*0)+(6*9)+(5*3)+(4*5)+(3*1)+(2*2)+(1*8)=112
112 % 10 = 2
So 109351-28-2 is a valid CAS Registry Number.

Synthesis of α,β-Unsaturated Aldehydes through Palladium Catalyzed Regioselective Hydrogen Migration
Minami, Tatsuya,Hanaoka, Miyoji
, p. 9425 - 9428 (2007/10/02)
Treatment of cyclic carbonate of 3-alkene-1,2-diols or 4-methylcarbonate of 2-alkene-1,4-diols with a catalytic amount of Pd(PPh3)4 in aqueous THF or AcOH gave α,β-unsaturated aldehydes in good yields.The reaction can be interpreted by the regioselective 1,4-hyrogen migration of ?-allylpalladium intermediate.
