1620137-43-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1620137-43-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,3 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1620137-43:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*3)+(3*7)+(2*4)+(1*3)=120
120 % 10 = 0
So 1620137-43-0 is a valid CAS Registry Number.

Synthesis of novel cinchona-amino acid hybrid organocatalysts for asymmetric catalysis
Barrulas, Pedro,Benaglia, Maurizio,Burke, Anthony J.
, p. 923 - 935 (2014/07/22)
Three novel subclasses of cinchonidine derivatives coupled to diverse amino acids were prepared in very good overall yield and tested in a benchmark organocatalytic aldol reaction, between acetone and aromatic aldehydes. These subclasses are a family of a
