Check Digit Verification of cas no
The CAS Registry Mumber 61593-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,5,9 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 61593-21:
(7*6)+(6*1)+(5*5)+(4*9)+(3*3)+(2*2)+(1*1)=123
123 % 10 = 3
So 61593-21-3 is a valid CAS Registry Number.

Bisphosphine oxide monomers
-
, (2008/06/13)
Bisphosphine oxide monomers and homologs thereof may be incorporated into polycarbonates in order to obtain a flame retardant polymer. More particularly, bis[2,5-(diphenylphosphine oxide)]-1,4-hydroquinone and homologs thereof may be used to prepare flame retardant polycarbonates that retain high glass transition temperature and high impact resistances.
