Check Digit Verification of cas no

The CAS Registry Mumber 144784-01-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,8 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144784-01:
(8*1)+(7*4)+(6*4)+(5*7)+(4*8)+(3*4)+(2*0)+(1*1)=140
140 % 10 = 0
So 144784-01-0 is a valid CAS Registry Number.

A New Xanthone Synthesis from the Diels-Alder Reaction between 2-Vinylchromen-4-ones and Cyclopentanone Enamine

Letcher, Roy M.,Yue, Tai-Yuen

, p. 1310 - 1311 (2007/10/02)

The reaction between 2-vinylchromen-4-ones and 1-pyrrolidinylcyclopentene give substituted 2,3,3a,4-tetrahydrocyclopentaxanthen-11(5H)-ones; the stereochemistry of the product shows that the initial step in the reaction may be considered to be an exo-addition Diels-Alder with inverse electron demand.
