Check Digit Verification of cas no
The CAS Registry Mumber 208941-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,9,4 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 208941-53:
(8*2)+(7*0)+(6*8)+(5*9)+(4*4)+(3*1)+(2*5)+(1*3)=141
141 % 10 = 1
So 208941-53-1 is a valid CAS Registry Number.

Pd-mediated C-C and C-S bond formation on solid support: A scope and limitations study
Wendeborn, Sebastian,Berteina, Sabine,Brill, Wolfgang K.-D.,De Mesmaeker, Alain
, p. 671 - 675 (1998)
The scope and limitations of Pd(0)-mediated coupling reactions between aromatic halides linked to a polystyrene resin and boronic acid derivatives (Suzuki coupling), aromatic and vinylic tin compounds (Stille coupling), as well as thiols are reported. For all reactions, conditions were optimized and evaluated with various reagents. In many cases, upon cleavage from the solid support, products were obtained in excellent yields. In most cases, the optimized reaction conditions are superior to those previously reported in the literature.
