131802-12-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131802-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,8,0 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131802-12:
(8*1)+(7*3)+(6*1)+(5*8)+(4*0)+(3*2)+(2*1)+(1*2)=85
85 % 10 = 5
So 131802-12-5 is a valid CAS Registry Number.

Cycloadditions of Alkynyl Esters and Ethers with 1,2,3-Tri-t-butyl Azete

Maas, Gerhard,Regitz, Manfred,Rahm, Rainer,Schneider, Juergen,Stang, Peter J.,Crittell, Charles M.

, p. 1456 - 1457 (2007/10/02)

Moderately electron-rich alkynes, such as alkynyl carboxylates 2a, b, siloxyalkynes 2c, d, an alkynyl p-toluenesulphonate 2e, and ethoxyacetylene 2f, add exclusively to the C=N bond of the kinetically stabilized azete 1; with terminal alkynes 2a, f, a mixture of the regioisomeric 1-Dewar-pyridines 3 and 4 is obtained, whereas addition of internal alkynes results only in 3-oxy-1-Dewar-pyridines 3.
