97305-90-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97305-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,3,0 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97305-90:
(7*9)+(6*7)+(5*3)+(4*0)+(3*5)+(2*9)+(1*0)=153
153 % 10 = 3
So 97305-90-3 is a valid CAS Registry Number.

N-Alkylation of some Secondary Styryl Enamides
Brettle, Roger,Shibib, Sa'ad M.,Wheeler, Kevin J.
, p. 831 - 836 (2007/10/02)
The preparation of some secondary styryl enamides of both the Z-and E-configuration, and their exclusively N-alkylation through their anions is described.Partial configurational inversion is observed under certain conditions during the alkylation of the d
