55636-11-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55636-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,3 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 55636-11:
(7*5)+(6*5)+(5*6)+(4*3)+(3*6)+(2*1)+(1*1)=128
128 % 10 = 8
So 55636-11-8 is a valid CAS Registry Number.

Facile synthesis of 4-arylidene-5-imidazolinones as synthetic analogs of fluorescent protein chromophore

Lee, Cheng-Yu,Chen, Yun-Chung,Lin, Hao-Chun,Jhong, Yuandong,Chang, Chih-Wei,Tsai, Ching-Hua,Kao, Chai-Lin,Chien, Tun-Cheng

A facile and effective synthesis for a wide variety of 4-arylidene-5- imidazolinone derivatives was developed. 4-Arylidene-5-oxazolinones were prepared by Erlenmeyer azlactone synthesis from N-acylglycines and arylaldehydes. The ring-opening reactions of the 4-arylidene-5-oxazolinones with primary amines afforded 2-acylamino-3-arylacrylamides in excellent yields. A new dehydrative cyclization of the 2-acylamino-3-arylacrylamides in pyridine under reflux furnished the corresponding 4-arylidene-5-imidazolinones in good yields.
