7504-51-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7504-51-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,0 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7504-51:
(6*7)+(5*5)+(4*0)+(3*4)+(2*5)+(1*1)=90
90 % 10 = 0
So 7504-51-0 is a valid CAS Registry Number.

Ru(II)-catalyzed [2 + 2 + 2] cycloaddition of 1,2-bis(propiolyl)benzenes with monoalkynes leading to substituted anthraquinones
Yamamoto, Yoshihiko,Hata, Koichi,Arakawa, Takayasu,Itoh, Kenji

[2 + 2 + 2] cycloadditions of 1,2-bis(propiolyl)benzenes with monoalkynes were effectively catalysed by Cp*RuCl(cod) under mild conditions to give substituted anthraquinones in moderate to high yields.
