90696-40-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90696-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,9 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90696-40:
(7*9)+(6*0)+(5*6)+(4*9)+(3*6)+(2*4)+(1*0)=155
155 % 10 = 5
So 90696-40-5 is a valid CAS Registry Number.

Synthesis of N-(triisopropylsilyl)- and N-(tert-butyldimethylsilyl)aldimines and their application in the synthesis of β-lactams

Cainelli, Gianfranco,Giacomini, Daria,Galletti, Paola

, p. 886 - 890 (1997)

A new and efficient synthesis of N-(TIPS)imines and N-(TBDMS)-imines starting from enolizable and non-enolizable aldehydes is described. We tested the reactivity of these imines in the preparation of β-lactams. N-(TBDMS)imines effectively give N-(TBDMS)azetidinones with a trans stereochemistry of the ring substituents, complementing N-(TMS)imines which instead afford cis β-lactams. In contrast, N-(TIPS)imines react with ester enolates in few cases because of the extremely low rate of the ring-closure step, so that a decomposition of enolates occurred.
