Check Digit Verification of cas no

The CAS Registry Mumber 301354-42-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,1,3,5 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 301354-42:
(8*3)+(7*0)+(6*1)+(5*3)+(4*5)+(3*4)+(2*4)+(1*2)=87
87 % 10 = 7
So 301354-42-7 is a valid CAS Registry Number.

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

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.
