Check Digit Verification of cas no
The CAS Registry Mumber 1004112-67-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,4,1,1 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1004112-67:
(9*1)+(8*0)+(7*0)+(6*4)+(5*1)+(4*1)+(3*2)+(2*6)+(1*7)=67
67 % 10 = 7
So 1004112-67-7 is a valid CAS Registry Number.

SYNTHESIS OF DIFLUOROMETHYL ETHERS AND SULFIDES
-
Paragraph 00167-00172; 00181-00184, (2014/07/22)
The synthesis of difluoromethyl ethers and sulfides with a simple, non-ozone- depleting reagent is described. The difluoromethylation of phenols with this reagent occurs at room temperature within minutes with exceptional functional group tolerance. The mild conditions makes possible tandem processes for the conversion of aryl boronic acids, aryl halides and arenes to difluoromethyl ethers. Mechanistic studies support a reaction pathway involving nucleophilic attack of the phenolate to difluorocarbene.
