Check Digit Verification of cas no

The CAS Registry Mumber 1431978-52-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,9,7 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1431978-52:
(9*1)+(8*4)+(7*3)+(6*1)+(5*9)+(4*7)+(3*8)+(2*5)+(1*2)=177
177 % 10 = 7
So 1431978-52-7 is a valid CAS Registry Number.

Intramolecular PdII-catalyzed dehydrogenative C(sp 3)-C(sp2) coupling: An alternative to Pd 0-catalyzed C(sp3)-H arylation from aryl halides?

Pierre, Cathleen,Baudoin, Olivier

, p. 4473 - 4478 (2013/06/26)

The synthesis of fused thiophene-cyclopentanes by PdII-catalyzed dehydrogenative C(sp2)-H/C(sp3)-H coupling is described. This reaction shows interesting chemo- and diastereoselectivity, however a direct comparison showed that it is yet much less efficient than the two-step sequence composed of electrophilic halogenation and Pd0-catalyzed C(sp3)-H arylation.
