Check Digit Verification of cas no

The CAS Registry Mumber 1256543-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,5,4 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1256543-75:
(9*1)+(8*2)+(7*5)+(6*6)+(5*5)+(4*4)+(3*3)+(2*7)+(1*5)=165
165 % 10 = 5
So 1256543-75-5 is a valid CAS Registry Number.

Oxidative oxo Diels-Alder reactions of Baylis-Hillman adducts with electron-rich alkenes in the presence of IBX

Yang, Jing,Li, Heping,Shi, Bo,Tian, Shengzhi,Zhang, Juan

experimental part, p. 1567 - 1576 (2012/05/04)

Baylis-Hillman adducts were oxidized by iodoxybenzoic acid (IBX) to 2-methylene-1,3-dicarbonyl compounds, which can act as oxodiene to react with electron-rich alkenes to generate a variety of oxo Diels-Alder adducts in good yields. Copyright Taylor & Fra

Water mediated trapping of active methylene intermediates generated by IBX-induced oxidation of Baylis-Hillman adducts with nucleophiles

Tan, Jia-Neng,Li, Haoquan,Gu, Yanlong

supporting information; experimental part, p. 1772 - 1782 (2011/02/21)

Water proved to be an efficient solvent for oxidation of a Baylis-Hillman adduct with IBX. The generated product, a methylene intermediate, could be trapped in situ by many nucleophiles in water, such as styrenes, β-dicarbonyl compounds, benzamide and les
