Check Digit Verification of cas no
The CAS Registry Mumber 138907-03-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,0 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138907-03:
(8*1)+(7*3)+(6*8)+(5*9)+(4*0)+(3*7)+(2*0)+(1*3)=146
146 % 10 = 6
So 138907-03-6 is a valid CAS Registry Number.

Enantioselective synthesis of 2,3-diamino acids by the bislactim ether method
Hartwig,Mittendorf
, p. 939 - 941 (2007/10/02)
A method is described for the asymmetric synthesis of both enantiomers of 2-alkyl-substituted 2,3-diaminopropionic acids with different protecting groups using the Schollkopf-Hartwig bislactim ether method, starting from 2-alkyl-2,5-dihydro-5-isopropyl-3,
