Check Digit Verification of cas no

The CAS Registry Mumber 25220-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,2 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25220-23:
(7*2)+(6*5)+(5*2)+(4*2)+(3*0)+(2*2)+(1*3)=69
69 % 10 = 9
So 25220-23-9 is a valid CAS Registry Number.

An efficient synthesis of trisubstituted oxazoles via chemoselective O-acylations and intramolecular Wittig reactions

Tsai, Yi-Ling,Fan, Yu-Shiou,Lee, Chia-Jui,Huang, Chan-Hui,Das, Utpal,Lin, Wenwei

supporting information, p. 10266 - 10268 (2013/10/22)

Preparation of new types of trisubstituted oxazoles is realized via chemoselective O-acylations and intramolecular Wittig reactions with ester functionalities using in situ formed phosphorus ylides as key intermediates. A plausible reaction mechanism for this undiscovered chemistry is also proposed based on the existence of expected and rearranged isomeric oxazoles.
