Check Digit Verification of cas no

The CAS Registry Mumber 1384247-68-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,4,2,4 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1384247-68:
(9*1)+(8*3)+(7*8)+(6*4)+(5*2)+(4*4)+(3*7)+(2*6)+(1*8)=180
180 % 10 = 0
So 1384247-68-0 is a valid CAS Registry Number.

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

supporting information; experimental part, p. 5898 - 5907 (2012/09/07)

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.
