Check Digit Verification of cas no

The CAS Registry Mumber 797801-56-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,7,8,0 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 797801-56:
(8*7)+(7*9)+(6*7)+(5*8)+(4*0)+(3*1)+(2*5)+(1*6)=220
220 % 10 = 0
So 797801-56-0 is a valid CAS Registry Number.

FUNCTIONALIZED BENZOXAZINES, POLYMERS AND COPOLYMERS THEREOF

-

Page 15,16, (2010/02/09)

The present invention relates to monofunctional benzoxazines having non-benzoxazine functional groups thereon. Polymers of benzoxazine can be formed from the monomers through functional group polymerization as well as benzoxazine polymerization utilizing the same or different mechanisms. The functionalized benzoxazine materials are high performance polymers having glass transition temperature about 200° C and which exhibit other desirable properties such as increase of char yield without a significant increase in viscosity of the monomer. Furthermore, the functionalized benzoxazine monomers can be copolymerized with other monomers such as epoxy. The benzoxazine copolymers exhibit toughness, processability, and excellent thermal properties.
