Check Digit Verification of cas no

The CAS Registry Mumber 57372-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,3,7 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57372-69:
(7*5)+(6*7)+(5*3)+(4*7)+(3*2)+(2*6)+(1*9)=147
147 % 10 = 7
So 57372-69-7 is a valid CAS Registry Number.

Aromatic ethers and process for producing aromatic ethers

-

Page 13-14, (2010/02/08)

According to a production process, aromatic ethers are producible by reacting phenols with an oxirane compound with use of an anion exchange resin as a catalyst. According to another production process, aromatic ethers having an alcoholic hydroxyl group are producible by a crystallization-purification step of using a solvent having a solubility parameter ranging from 7.5 to 12.5 for purification by crystallization. Further, according to still another production process, producible are aromatic ethers having an alcoholic hydroxyl group, wherein the content of a metal in the aromatic ethers is less than 100 ppm by mass, and the content of a halogen element in the aromatic ethers is less than 100 ppm by mass.
