Check Digit Verification of cas no
The CAS Registry Mumber 4400-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4400-05:
(6*4)+(5*4)+(4*0)+(3*0)+(2*0)+(1*5)=49
49 % 10 = 9
So 4400-05-9 is a valid CAS Registry Number.

Selective and efficient generation of ortho-brominated para-substituted phenols in ACS-grade methanol
Georgiev, David,Saes, Bartholomews W.H.,Johnston, Heather J.,Boys, Sarah K.,Healy, Alan,Hulme, Alison N.
, (2016/02/05)
The mono ortho-bromination of phenolic building blocks by NBS has been achieved in short reaction times (15-20 min) using ACS-grade methanol as a solvent. The reactions can be conducted on phenol, naphthol and biphenol substrates, giving yields of >86% on gram scale. Excellent selectivity for the desired mono ortho-brominated products is achieved in the presence of 10 mol % para-TsOH, and the reaction is shown to be tolerant of a range of substituents, including CH3/ F,and NHBoc.
