The CAS Registry Mumber 193546-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,5,4 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 193546-38:
(8*1)+(7*9)+(6*3)+(5*5)+(4*4)+(3*6)+(2*3)+(1*8)=162
162 % 10 = 2
So 193546-38-2 is a valid CAS Registry Number.

Synthesis of chirally pure 2,5-disubstituted diketopiperazines derived from trisubstituted phenylalanines

Danthi, Satyavijayan Narasimhan,Hill, Ronald A.

, p. 835 - 844 (2007/10/03)

Some new chirally pure 2,5-substituted diketopiperazines were synthesized starting from 2-methoxybenzyl alcohol. This multistep synthesis proceeds through the enzymatic synthesis of chirally pure amino acids, protection and dipeptide coupling, cyclization of dipeptide ester formates, and nitration of the resulting diketopiperazines.
