Check Digit Verification of cas no

The CAS Registry Mumber 175854-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,8,5 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 175854-88:
(8*1)+(7*7)+(6*5)+(5*8)+(4*5)+(3*4)+(2*8)+(1*8)=183
183 % 10 = 3
So 175854-88-3 is a valid CAS Registry Number.

Trimethylsilyl Nitronates Derived from 2-Substituted Nitroethanes in δ-Elimination Reactions

Ioffe, S. L.,Makarenkova, L. M.,Strelenko, Yu. A.,Tartakovskii, V. A.

, p. 1099 - 1103 (2007/10/03)

Silylation of β-substituted nitroethanes XCH2CH2NO2 (X=Cl or OCOCH3) with conventional silylating agents yields corresponding trimethylsilyl nitronates which undergo δ-elimination of nitroethylene under the reaction conditions.Stable silyl nitronates containing one or two trimethylsilyl groups were isolated in the silylation of C6H5NHCH2CH2NO2. 1,3-Dipolar cycloaddition of the nitronates to methoxide ion results in formation of 5-methoxycarbonyl-3-phenylaminomethyl(or 3-N-trimethylsilylphenylaminomethyl)-3-trimethylsiloxyisoxazolidines.Thermolysis of the latter affords 5-methoxycarbonyl-2-isoxazoline.
