1193338-87-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1193338-87-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,3,3,3 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1193338-87:
(9*1)+(8*1)+(7*9)+(6*3)+(5*3)+(4*3)+(3*8)+(2*8)+(1*7)=172
172 % 10 = 2
So 1193338-87-2 is a valid CAS Registry Number.

Novel polymers of intrinsic microporosity (PIMs) derived from 1,1-spiro-bis(1,2,3,4-tetrahydronaphthalene)-based monomers

Carta, Mariolino,Msayib, Kadhum J.,McKeown, Neil B.

supporting information; experimental part, p. 5954 - 5957 (2010/01/18)

The synthesis of novel monomers based upon the rigid 1,1′-spiro-bis(1,2,4,5-tetrahydro-6,7-dihydroxynaphthalene) framework is reported. These monomers can be used for the synthesis of polymers of intrinsic microporosity (PIMs) due to their reactive catech
