Check Digit Verification of cas no

The CAS Registry Mumber 1417564-53-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,5,6 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1417564-53:
(9*1)+(8*4)+(7*1)+(6*7)+(5*5)+(4*6)+(3*4)+(2*5)+(1*3)=164
164 % 10 = 4
So 1417564-53-4 is a valid CAS Registry Number.

One-pot synthesis of 2-aryl-3-alkoxycarbonyl chromones through a cascade Lewis acid-catalyzed aldehyde olefination/oxa-Michael addition/oxidation

Wang, Ningning,Cai, Shuying,Zhou, Chao,Lu, Ping,Wang, Yanguang

, p. 647 - 652 (2013/07/25)

2-Aryl-3-alkoxycarbonyl chromones were effectively constructed from aryl aldehydes and 3-(2-(methoxymethoxy) phenyl)propiolates via a cascade Lewis acid catalyzed phenol ether deprotection/aldehyde olefination/intramolecular oxa-Michael addition reaction, and a sequential oxidation. This four-step reaction could be conducted in one-pot with high atom efficiency.
