162189-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 162189-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,1,8 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 162189-45:
(8*1)+(7*6)+(6*2)+(5*1)+(4*8)+(3*9)+(2*4)+(1*5)=139
139 % 10 = 9
So 162189-45-9 is a valid CAS Registry Number.

Natural product-derived building blocks for combinatorial synthesis. Part 1. Fragmentation of natural products from myxobacteria

Niggemann, Jutta,Michaelis, Katrin,Frank, Ronald,Zander, Norbert,Hoefle, Gerhard

, p. 2490 - 2503 (2007/10/03)

Novel and unique chiral building blocks of high structural diversity were obtained by selective chemical fragmentation of natural products from myxobacteria. Subsequent modification reactions provided primary alcohol and carboxylic acid derivatives, which are suitable for the construction of combinatorial chemical libraries. The single SPOT synthesis of a hybrid structure on a polypropylene membrane was employed to demonstrate the chemical recombination of such rare building blocks on a micro-scale.
