99297-17-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99297-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,9 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99297-17:
(7*9)+(6*9)+(5*2)+(4*9)+(3*7)+(2*1)+(1*7)=193
193 % 10 = 3
So 99297-17-3 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
