227473-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 227473-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,4,7 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 227473-75:
(8*2)+(7*2)+(6*7)+(5*4)+(4*7)+(3*3)+(2*7)+(1*5)=148
148 % 10 = 8
So 227473-75-8 is a valid CAS Registry Number.

Cross coupling strategies towards the synthesis of the streptonigrin CD moiety
Crous, Renier,Dwyer, Catherine,Holzapfel, Cedric W.
, p. 721 - 726 (2007/10/03)
An efficient route to an appropriate model of the streptonigrin 4- phenylpyridine CD moiety is reported. 4-Chloro-3-nitropyridine was found to be the key precursor and its reactivity in cross coupling reactions was further investigated.
