Check Digit Verification of cas no

The CAS Registry Mumber 62703-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,7,0 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 62703-77:
(7*6)+(6*2)+(5*7)+(4*0)+(3*3)+(2*7)+(1*7)=119
119 % 10 = 9
So 62703-77-9 is a valid CAS Registry Number.

Coordination Compounds of Tantalum(V)

Mookerjee, M. N.,Singh, R. V.,Tandon, J. P.

, p. 521 - 522 (2007/10/02)

Ta(OPri)4(SB), Ta(OPri)3(SB)2 and Ta(OPRi)2(SB)3 types of complexes of tantalum with aldimines (SBH) of the type o-OHC6H4CH:NC6H4CH3-o, o-OHC6H4CH:NC4H9-n, C6H5CH:NNHCONH2 and C6H5CH:NNHCSNH2 have been synthesized by the reactions of tantalum pentaisopropoxide.The aldimines were obtained by the condensation of salicylaldehyde with o-methylaniline and n-butylamine and of benzaldehyde with semicarbazide hydrochloride and thiosemicarbazide.The complexes have been fully characterised by their analytical data, conductance, magnetic and molecular weight measurement and IR, electronic and PMR data.
