97550-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97550-55-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,5 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97550-55:
(7*9)+(6*7)+(5*5)+(4*5)+(3*0)+(2*5)+(1*5)=165
165 % 10 = 5
So 97550-55-5 is a valid CAS Registry Number.

OPTICAL ACTIVITY OF LACTONES AND LACTAMS-IV CHIROPTICAL PROPERTIES OF 4-IMIDAZOLIDINONES
Polonski, T.
, p. 611 - 616 (2007/10/02)
The chiroptical properties of 4-imidazolidinones are reviewed.Several optically active compounds were obtained from amides and N-methylamides of corresponding N-acylamino acids.The origin of the two lowest energy electronic transitions is considered.The e
