190259-54-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 190259-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,2,5 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 190259-54:
(8*1)+(7*9)+(6*0)+(5*2)+(4*5)+(3*9)+(2*5)+(1*4)=142
142 % 10 = 2
So 190259-54-2 is a valid CAS Registry Number.

, p. 73 - 87 (2007/10/03)
A rhodium carbonyl complex, [RhCl(CO)2]2, serves as a catalyst of the intra- and inter-molecular Pauson-Khand reaction. By the use of the rhodium catalyst, cyclopentenone derivatives are prepared from various 1,6- and 1,7-enynes unde
