103903-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103903-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,9,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103903-20:
(8*1)+(7*0)+(6*3)+(5*9)+(4*0)+(3*3)+(2*2)+(1*0)=84
84 % 10 = 4
So 103903-20-4 is a valid CAS Registry Number.

Coville, Neil J.,Harris, Gillian W.,Rehder, Dieter
, p. 365 - 370 (1985)
The reaction between (η5-C5H5)V(CO)4 and RNC in the presence of PdO as catalyst to give (η5-C5H5)V(CO)4-n(CNR)n (n=1-3) is reported.The complexes have been characterized by IR and 51V and 1H NMR spectroscopy.
