254444-48-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 254444-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,4,4 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 254444-48:
(8*2)+(7*5)+(6*4)+(5*4)+(4*4)+(3*4)+(2*4)+(1*8)=139
139 % 10 = 9
So 254444-48-9 is a valid CAS Registry Number.

Mateo, Cristina,Cardenas, Diego J.,Martin-Matute, Belen,Echavarren, Antonio M.
, p. 2205 - 2206 (2007/10/03)
Alkylarylcuprates with intramolecularly tethered stannanes undergo an intracluster Cu(I)/Sn(IV) transmetalation to yield arylstannanes.
