Check Digit Verification of cas no

The CAS Registry Mumber 103993-12-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,9,9 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 103993-12:
(8*1)+(7*0)+(6*3)+(5*9)+(4*9)+(3*3)+(2*1)+(1*2)=120
120 % 10 = 0
So 103993-12-0 is a valid CAS Registry Number.

Lewis Acid Mediated Claisen-Type Rearrangement of Aryl Dienyl Ethers

Maruyama, Kazuhiro,Nagai, Naoshi,Naruta, Yoshinori

, p. 5083 - 5092 (1986)

Rearrangement of aryl pentadienyl ethers in the presence of BF3*OEt2 affords pentadienyl phenols in good yields without formation of the corresponding rearranged products.The mechanism of this rearrangement was studied by deuterium labeling and cross-coupling reactions.The scope and limitations of the rearrangement are discussed.
