Check Digit Verification of cas no

The CAS Registry Mumber 84500-58-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,0 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84500-58:
(7*8)+(6*4)+(5*5)+(4*0)+(3*0)+(2*5)+(1*8)=123
123 % 10 = 3
So 84500-58-3 is a valid CAS Registry Number.

Transition Metal Ketene Compounds, XIV. Phosphino- and Arsinoketenes - Novel Ligands in Transition Metal Complexes

Wolfgruber, Mathias,Sieber, Werner,Kreissl, Fritz R.

, p. 427 - 433 (2007/10/02)

The first synthesis of phosphorus and arsenic substituted ketenes and its stabilization as novel ligands in transition metal complexes (2a - 5b) succeeded on reacting η2-ketenyl complexes η5-C5H5(CO)W2-C(R)CO> (1a, 1b) with alkyl- or arylhalogenphosphanes and -arsanes.This addition-rearrangement reaction proceeds at least in case of the phosphorus substituted representatives via isolable intermediates, where the phosphinoketenes act as η3-ligands.
