Check Digit Verification of cas no

The CAS Registry Mumber 16175-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,7 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16175-01:
(7*1)+(6*6)+(5*1)+(4*7)+(3*5)+(2*0)+(1*1)=92
92 % 10 = 2
So 16175-01-2 is a valid CAS Registry Number.

Manganese-catalyzed cross-coupling of thiols with aryl iodides

Liu, Tsung-Jui,Yi, Chih-Lun,Chan, Chien-Ching,Lee, Chin-Fa

, p. 1029 - 1034 (2013/08/25)

A manganese-catalyzed cross-coupling reaction of thiols with aryl iodides, furnishing aryl thioethers in good to excellent yields has been reported; the system shows good functional group tolerance and enables the sterically demanding aryl iodides to couple with thiols. Coming up for ArI: A manganese-catalyzed cross-coupling reaction of thiols with aryl iodides that furnishes aryl thioethers in good to excellent yields has been reported. Functional groups such as unprotected alcohols and chloro substituents are tolerated under these reaction conditions. Moreover, this catalytic system enables the sterically demanding aryl iodides to couple with thiols (see scheme; R=aryl or alkyl).

One aspect of the present invention relates to copper-catalyzed carbon-heteroatom and carbon-carbon bond-forming methods. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-sulfur bond between the sulfur atom of a thiol moiety and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In other embodiments, the present invention relates to copper(II)-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of an amide and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-carbon bond between the carbon atom of cyanide ion and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In another embodiment, the present invention relates to a copper-catalyzed method of transforming and aryl, heteroaryl, or vinyl iodide. Yet another embodiment of the present invention relates to a tandem method, which may be practiced in a single reaction vessel, wherein the first step of the method involves the copper-catalyzed formation of an aryl, heteroaryl, or vinyl iodide from the corresponding aryl, heteroaryl, or vinyl chloride or bromide; and the second step of the method involves the copper-catalyzed formation of an aryl, heteroaryl, or vinyl nitrile, amide or sulfide from the aryl, heteroaryl, or vinyl iodide formed in the first step.
