Check Digit Verification of cas no

The CAS Registry Mumber 18461-40-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,6 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18461-40:
(7*1)+(6*8)+(5*4)+(4*6)+(3*1)+(2*4)+(1*0)=110
110 % 10 = 0
So 18461-40-0 is a valid CAS Registry Number.

SYNTHESIS AND INFRARED STUDY OF (C6H5)nPX3-nCr(CO)5 (X=Cl, Br, I, H; n=0-3) AND (C6H5)2PRCr(CO)5 (R=METHYL, ETHYL, i-PROPYL, t-BUTYL) COMPOUNDS

Vincent, E.,Verdonck, L.,Kelen, G. P. van der

, p. 33 - 40 (2007/10/02)

A method for the preparation of (C6H5)nPX3-nCr(CO)5 complexes in the crystalline state is described.The carbon-oxygen stretching vibration, νCO(A1 eq.), of the complexes with X=Cl, Br, I is mainly determined by the inductive effect of the (C6H5)nPX3-n group.For X=H, the νCO band is defined by the concomitant influence of the ?, ? and steric effects.
