Check Digit Verification of cas no

The CAS Registry Mumber 1253261-54-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,2,6 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1253261-54:
(9*1)+(8*2)+(7*5)+(6*3)+(5*2)+(4*6)+(3*1)+(2*5)+(1*4)=129
129 % 10 = 9
So 1253261-54-9 is a valid CAS Registry Number.

Convergent synthesis of geometrically disassembling dendrimers using Cu(I)-catalyzed C-O bond formation

Polaske, Nathan W.,Szalai, Michael L.,Shanahan, Charles S.,McGrath, Dominic V.

supporting information; experimental part, p. 4944 - 4947 (2010/12/25)

The convergent synthesis of geometrically degradable dendrimers based on the 2,4-bis(hydroxymethyl)phenol subunit is presented. The key step of the synthetic scheme involves the CuI/3,4,7,8-tetramethyl-1,10-phenanthroline- catalyzed coupling of aryl iodides and alcohols. The synthesis and disassembly of these compounds is discussed.
