77655-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77655-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,5 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77655-22:
(7*7)+(6*7)+(5*6)+(4*5)+(3*5)+(2*2)+(1*2)=162
162 % 10 = 2
So 77655-22-2 is a valid CAS Registry Number.

Studies on Infrared Spectra of some Azalactones
Dhoubhadel, S. P.
, p. 757 - 758 (2007/10/02)
Infrared spectra of some 4-(p-substituted-benzylidene)-2-phenyl-5-oxazolones have been studied with reference to frequency of CN and C=O groups of the ring, which were not significantly influenced by variations of the para-substituent.
