Check Digit Verification of cas no

The CAS Registry Mumber 157470-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,7 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 157470-19:
(8*1)+(7*5)+(6*7)+(5*4)+(4*7)+(3*0)+(2*1)+(1*9)=144
144 % 10 = 4
So 157470-19-4 is a valid CAS Registry Number.

Synthesis and structure of the phosphinophosphide niobocene complex Cp2Nb(PPh2)(PHPh2)

Nikonov, Georgii I.,Lemenovskii, Dmitry A.,Dorogov, Konstantin Yu.,Churakov, Andrei V.

, p. 1159 - 1162 (1999)

The phosphinophosphido niobocene complex Cp2Nb(PHPh2)(PPh2) (2) was prepared by deprotonation of the cationic diphosphino complex [Cp2Nb(PHPh2)2]Cl (3). Complex 2 is thermally unstable and readily dissociates phosphine to give the ortho-metallated complex Cp2Nb(PHPhC6H4-). Crystal structure determination of 2 supported its formulation as the phosphinophosphido compound. The Nb-P(1) (phosphino) bond length is 2.524(2) A and Nb-P(2) (phosphido) bond length is 2.610(2) A.
