1159172-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1159172-45-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,9,1,7 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1159172-45:
(9*1)+(8*1)+(7*5)+(6*9)+(5*1)+(4*7)+(3*2)+(2*4)+(1*5)=158
158 % 10 = 8
So 1159172-45-8 is a valid CAS Registry Number.

Diastereoselective Ritter reactions of chiral secondary benzylic alcohols
Rubenbauer, Philipp,Bach, Thorsten
supporting information; experimental part, p. 2130 - 2132 (2009/09/06)
An acid-catalysed Ritter reaction of chiral secondary benzylic alcohols enables diastereoselective access to chiral amides, which represent inter alia valuable intermediates for the synthesis of chiral 1,2-diamines and β-amino acids.
