51209-84-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51209-84-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,2,0 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 51209-84:
(7*5)+(6*1)+(5*2)+(4*0)+(3*9)+(2*8)+(1*4)=98
98 % 10 = 8
So 51209-84-8 is a valid CAS Registry Number.

Fe-promoted cross coupling of homobenzylic methyl ethers with Grignard reagents via sp3 C-O bond cleavage

Luo, Shuang,Yu, Da-Gang,Zhu, Ru-Yi,Wang, Xin,Wang, Lei,Shi, Zhang-Jie

, p. 7794 - 7796 (2013/09/02)

The first iron-catalyzed formal cross coupling of homobenzylic methyl ethers with alkyl Grignard reagents is realized. The reaction is proposed to proceed through a sequence of dehydroalkoxylation to form the vinyl-intermediate, followed by Fe-catalyzed selective carbometalation to form a benzylic Grignard reagent.
