Check Digit Verification of cas no

The CAS Registry Mumber 1207288-82-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,2,8 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1207288-82:
(9*1)+(8*2)+(7*0)+(6*7)+(5*2)+(4*8)+(3*8)+(2*8)+(1*2)=151
151 % 10 = 1
So 1207288-82-1 is a valid CAS Registry Number.

Gold-catalyzed rearrangement of allylic oxonium ylides: Efficient synthesis of highly functionalized dihydrofuran-3-ones

Fu, Junkai,Shang, Hai,Wang, Zhaofeng,Chang, Le,Shao, Wenbing,Yang, Zhen,Tang, Yefeng

, p. 4198 - 4202 (2013/05/08)

"Diazo" not needed: The title reaction results in the rearrangement of oxonium ylides, which were prepared from readily available homopropargylic allylic ethers instead of diazo compounds, through two different mechanisms: a concerted 2,3-sigmatropic rearrangement, or a stepwise 1,4-allyl migration followed by a Claisen rearrangement (see scheme).
