Check Digit Verification of cas no
The CAS Registry Mumber 289039-26-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,0,3 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 289039-26:
(8*2)+(7*8)+(6*9)+(5*0)+(4*3)+(3*9)+(2*2)+(1*6)=175
175 % 10 = 5
So 289039-26-5 is a valid CAS Registry Number.

The Catalyst-Controlled Regiodivergent Chlorination of Phenols

Different catalysts are demonstrated to overcome or augment a substrate's innate regioselectivity. Nagasawa's bis-thiourea catalyst was found to overcome the innate para-selectivity of electrophilic phenol chlorination, yielding ortho-chlorinated phenols that are not readily obtainable via canonical electrophilic chlorinations. Conversely, a phosphine sulfide derived from 2,2′-Bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) was found to enhance the innate para-preference of phenol chlorination.
