Check Digit Verification of cas no
The CAS Registry Mumber 29284-59-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,2,8 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29284-59:
(7*2)+(6*9)+(5*2)+(4*8)+(3*4)+(2*5)+(1*9)=141
141 % 10 = 1
So 29284-59-1 is a valid CAS Registry Number.

The microwave spectra of 79BrSCN and 81BrSCN have been measured and analysed to give rotational, centrifugal distorsion, and Br quadrupole coupling constants.The molecule has been shown unambiguously to be BrSCN rather than BrNCS.A harmonic force field has been determined from combined vibrational and distorsion data.With structural parameters for the SCN chain transferred from S(CN)2, both effective and ground state average values for the BrS length and BrSC angle have been estimated.The Br quadropole tensor haas been diagonalized, and the BrS bond is shown not to be bent.

The unstable chlorine and bromine thiocyanate molecules have been generated in the gas phase by reaction of AgSCN (solid) or (SCN)2 (gas) with molecular chlorine or bromine, respectively.ISCN does not appear to be formed by this route.The structures are established as nonlinear X-S-C(*)N molecules, and the observed HeI photoelectron spectra are assigned on this basis with the assistance of minimal basis ab initio calculations.The electronic structures of these molecules lie between those of SX2 and S(CN)2; the chemical behavior suggests an analogy with the interhalogen compounds.
