Check Digit Verification of cas no

The CAS Registry Mumber 1563186-91-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,3,1,8 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1563186-91:
(9*1)+(8*5)+(7*6)+(6*3)+(5*1)+(4*8)+(3*6)+(2*9)+(1*1)=183
183 % 10 = 3
So 1563186-91-3 is a valid CAS Registry Number.

Palladium-catalyzed stille-type coupling of N -acyl iminium ions with distannanes: A Multicomponent synthesis of α-amidostannanes

Xu, Boran,Arndtsen, Bruce A.

, p. 843 - 846 (2014/04/03)

The palladium-catalyzed three-component coupling of imines, acid chlorides, and hexabutyldistannane is described. This results in the synthesis of various α-amidostannanes in good yields, without the use of strong nucleophilic organometallic reagents. The reaction is believed to proceed via a Stille-type cross coupling of an in situ-generated N-acyl iminium salt with Bu 3SnSnBu3 and reaches completion within 1 h at ambient temperature using simple, unligated Pd2dba3 as a catalyst. Combining the formation of α-amidostannanes with lithiation and carboxylation allows the overall synthesis of amino acid derivatives in two steps from imines, acid chlorides, and CO2.
