123004-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123004-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,0 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123004-77:
(8*1)+(7*2)+(6*3)+(5*0)+(4*0)+(3*4)+(2*7)+(1*7)=73
73 % 10 = 3
So 123004-77-3 is a valid CAS Registry Number.

Total syntheses of (-)-nocardicins A-G: A biogenetic approach
Salituro, Gino M.,Townsend, Craig A.
, p. 760 - 770 (2007/10/02)
The known nocardicins A-G have been synthesized, several for the first time, having geometric and stereoisomeric purities of a high order. The syntheses proceed through the central intermediacy of tert-butyl (-)-3-aminocardicinate (14), which has been pre
