Check Digit Verification of cas no

The CAS Registry Mumber 1269423-38-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,4,2 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1269423-38:
(9*1)+(8*2)+(7*6)+(6*9)+(5*4)+(4*2)+(3*3)+(2*3)+(1*8)=172
172 % 10 = 2
So 1269423-38-2 is a valid CAS Registry Number.

Multiple sonogashira reactions of polychlorinated molecules. Synthesis and photophysical properties of the first pentaalkynylpyridines

Ehlers, Peter,Neubauer, Antje,Lochbrunner, Stefan,Villinger, Alexander,Langer, Peter

, p. 1618 - 1621 (2011)

Hitherto unknown pentaalkynylpyridines have been prepared in high yields by Sonogashira cross-coupling reactions of pentachloropyridine. Their photophysical properties were studied and compared to those of penta- and hexaalkynylbenzenes which were efficie
