53575-46-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53575-46-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,5,7 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 53575-46:
(7*5)+(6*3)+(5*5)+(4*7)+(3*5)+(2*4)+(1*6)=135
135 % 10 = 5
So 53575-46-5 is a valid CAS Registry Number.

Rhodium(III) porphyrin-catalyzed reactions via activation of alkynes

Hasegawa, Makoto,Kurahashi, Takuya,Matsubara, Seijiro

, p. 1937 - 1939 (2014)

The cycloisomerization of 1,6-enynes catalyzed by rhodium(III) porphyr in under mild reaction conditions successfully afforded a five-membered ring system. The rhodium porphyrin was found to be a strong π-Lewis acid that could activate alkynes. Thus, rhod
