Check Digit Verification of cas no

The CAS Registry Mumber 1228390-57-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,3,9 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1228390-57:
(9*1)+(8*2)+(7*2)+(6*8)+(5*3)+(4*9)+(3*0)+(2*5)+(1*7)=155
155 % 10 = 5
So 1228390-57-5 is a valid CAS Registry Number.

, p. 4051 - 4057 (2015)

Alkylation of rhodium porphyrins was achieved in moderate to high yields in the presence of air and water. With this facile alkylation method, various alkyl RhIII(por) species, including those with tertiary alkyl, were synthesized. Mechanistic

Carbon-nitrogen bond activation of amines by rhodium(III) porphyrin complexes

Au, Ching Chi,Lai, Tsz Ho,Chan, Kin Shing

, p. 1370 - 1374 (2010/07/04)

Carbon-nitrogen bond activation of amines by rhodium porphyrin chloride has been achieved to give rhodium porphyrin alkyl complexes. Rhodium porphyrin hydride and rhodium porphyrin dimer were proposed as the intermediates in cleaving the C-N bond.
