Check Digit Verification of cas no

The CAS Registry Mumber 142144-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,4 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142144-87:
(8*1)+(7*4)+(6*2)+(5*1)+(4*4)+(3*4)+(2*8)+(1*7)=104
104 % 10 = 4
So 142144-87-4 is a valid CAS Registry Number.

[3 + 2]-Cycloaddition reactions of alkynyl(phenyl)iodonium triflates with ethyl diazoacetate, N-t-butyl-α-phenyl nitrone and t-butylnitrileoxide as 1,3-dipoles

Slang, Peter J.,Murch, Paul

, p. 8793 - 8794 (1997)

The [3+2]-cycloaddition of various β-substituted ethynyliodonium salts, RC≡CI(+)OTf, with ethyl diazoacetate, N-t-butyl-a-phenyl nitrone and t-butylnitrile oxide results in single regioisomeric pyrroles, dihydroisoxozoles, and isoxazoles respectively in moderate yields.

1,3-Dipolar cycloaddition reactions of α-diazocarbonyl compounds, organoazides, and ethynyl(phenyl)iodonium triflate salts

Maas,Regitz,Moll,Rahm,Krebs,Hector,Stang,Crittell,Williamson

, p. 3527 - 3540 (2007/10/02)

The electron-poor triple bond of R-C≡I+-Ph·TfO- (1, R = H, SiMe3, tBuCO) undergoes [2+3] cycloaddition with α-diazocarbonyl compounds. Whereas 1:1 cycloadducts (4a-d,6) are obtained for R = SiMe3 or tBuCO (X-ray
