Check Digit Verification of cas no

The CAS Registry Mumber 135327-47-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,2 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 135327-47:
(8*1)+(7*3)+(6*5)+(5*3)+(4*2)+(3*7)+(2*4)+(1*7)=118
118 % 10 = 8
So 135327-47-8 is a valid CAS Registry Number.

Organotin esters of dithiocarbamylacetic acids

Ng, Seik Weng,Das, V. G. Kumar

, p. 143 - 156 (2007/10/02)

Twelve di- and tri-organotin derivatives of dithiocarbamylacetic acids of the formula RnSn(O2CCH2S2CNR'2)4-n (R = Me, nBu, cHex, Ph; NR'2 = NMe2, NEt2, N(CH2)4, N(CH2CH2)2O; n = 3, 2) have been prepared.On the basis of IR and Moessbauer spectroscopic data, the trimethyl-, tri-n-butyl- and triphenyltin derivatives are assigned a carboxylate-bridged structure with trans-C3SnO2 trigonal bipyramidal geometry at tin.The diorganotin dithiocarbamylacetates also adopt a bridged structure with a trans-C2SnO4 octahedral geometry at tin.The triorganotin esters dissociate into four-coordinate species in solution, as revealed by NMR (1H and 13C) spectral data.The tri-cyclohexyltin ester, however, are four-coordinate monomers in the solid state and in solution.Three distannoxanes, 2 (R''2Sn = Bu2Sn, BuPhSn, Ph2Sn), were obtained as adventituous products during attempts to make the diorganotin esters from the diorganotin dihalides; for these distannoxanes the spectral data are interpreted in terms of skew-trapezoidal bipyramidal coordination at the tin atoms.
