Check Digit Verification of cas no
The CAS Registry Mumber 4664-73-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4664-73:
(6*4)+(5*6)+(4*6)+(3*4)+(2*7)+(1*3)=107
107 % 10 = 7
So 4664-73-7 is a valid CAS Registry Number.

Dichloromethane as a chlorination reagent for α-bromocarbonyl compounds in the presence of a copper catalyst

We found that dichloromethane is a powerful chlorinating reagent for the congested 3° and 2° Csp3Br bond of α-bromocarbonyl amides, esters, and ketones. In the presence of an appropriate copper complex as a catalyst, the desired chlorination occurred within an hour. Control experiments revealed that in situ-generated CuCl2 is a key chlorinating agent that reacts with the 3° or 2° alkyl radicals generated by the reaction between an α-bromocarbonyl compound and a Cu(I) salt.
