Check Digit Verification of cas no

The CAS Registry Mumber 180594-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,5,9 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 180594-90:
(8*1)+(7*8)+(6*0)+(5*5)+(4*9)+(3*4)+(2*9)+(1*0)=155
155 % 10 = 5
So 180594-90-5 is a valid CAS Registry Number.

Preparation of a novel cross-linked polymer for second-order nonlinear optics

A novel cross-linked pyroelectric polymer with pronounced second-order nonlinear optical properties has been prepared. A multistep synthesis with several selective transformations including a kinetic resolution (transesterification) with the highly enantioselective Candida antarctica lipase B, yielded the monomer 4''-{(R)-(-)-2[(10-acryloyloxy)decyl]oxy}-3-nitrophenyl 4-{4'-[(11-acryloyloxy)undecyloxy]phenyl}benzoate A2c which displayed a ferroelectric chiral smectic C phase with large spontaneous polarization (175 nC/cm2). The monomer was poled and subsequently cross-linked by in-situ photopolymerization in the surface-stabilized ferroelectric liquid crystalline state. The cross-linked pyroelectric polymer exhibited an electro-optical coefficient (r22-r12) of 15-35 pm/V.
