Check Digit Verification of cas no

The CAS Registry Mumber 51531-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,3 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 51531-22:
(7*5)+(6*1)+(5*5)+(4*3)+(3*1)+(2*2)+(1*2)=87
87 % 10 = 7
So 51531-22-7 is a valid CAS Registry Number.

Ruthenium-catalysed double trans-hydrosilylation of 1,4-diarylbuta-1,3- diynes leading to 2,5-diarylsiloles

Matsuda, Takanori,Kadowaki, Sho,Murakami, Masahiro

, p. 2627 - 2629 (2007)

Dihydrosilanes undergo double trans-hydrosilylation with 1,4-diarylbuta-1,3-diynes in the presence of a cationic ruthenium catalyst to afford 2,5-diarylsiloles: in particular, 9-silafluorene is a good hydrosilylating agent to produce spiro-type siloles in good yield.
