104308-37-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 104308-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,0 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104308-37:
(8*1)+(7*0)+(6*4)+(5*3)+(4*0)+(3*8)+(2*3)+(1*7)=84
84 % 10 = 4
So 104308-37-4 is a valid CAS Registry Number.

C-Nitrosoformamides, a New Class of Transient Dienophiles Formed by Oxidation of N-Hydroxyureas

Christie, Clifford C.,Kirby, Gordon W.,McGuigan, Henry,Mackinnon, John W. M.

, p. 2469 - 2474 (2007/10/02)

Oxidation of hydroxyurea with sodium or tetraethylammonium periodate in the presence of cyclopentadiene gave a cycloadduct (3a) formed, apparently, by capture of the transient dienophile, C-nitrosoformamide.N-Methyl-, N-phenyl-, N,N-dimethyl-, and N,N-diphenyl-C-nitrosoformamide were likewise trapped as their cycloadducts with cyclopentadiene.Cycloadducts of 2,3-dimethylbuta-1,3-diene, thebaine, ergosteryl acetate, and 9,10-dimethylanthracene (DMA) were prepared similarly.The cyclopentadiene adducts (3) dissociated at 80 deg C in the presence of 2,3-dimethylbuta-1,3-diene to give the corresponding adducts (4) of the nitrosoformamides and dimethylbutadiene.Unexpectedly, the 1,4-adducts (4) were accompanied by substantial amounts of hydroxamic acids (5) arising from 'ene' reactions of the nitrosoformamides and dimethylbutadiene.The cyclopentadiene adducts of N,N-dimethyl- and N,N-diphenyl-C-nitrosoformamide, when heated alone, decomposed to give the corresponding carbamic anhydrides.The cycloadduct (15) of DMA and C-nitrosoformamide dissociated at 40 deg C in the presence of thebaine (11) to give the thebaine adduct (12; R=H) and DMA.
