Check Digit Verification of cas no

The CAS Registry Mumber 1143526-58-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,3,5,2 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1143526-58:
(9*1)+(8*1)+(7*4)+(6*3)+(5*5)+(4*2)+(3*6)+(2*5)+(1*8)=132
132 % 10 = 2
So 1143526-58-2 is a valid CAS Registry Number.

Palladium-catalyzed trimerizations of terminal arylalkynes: Synthesis of 1,3-diaryl-2-arylethynyl-1,3-butadienes

Wu, Yao-Ting,Lin, Wei-Chih,Liu, Chia-Ju,Wu, Chuan-Yi

experimental part, p. 1841 - 1849 (2009/08/07)

Various 1,3-diaryl-2-arylethynyl-1,3-butadienes 7 have been prepared by the Pd-catalyzed trimerization of arylalkynes 4. Their structures and stereochemistry have been confirmed by X-ray crystal analyses. This procedure provides high regioselectivity to g
