Check Digit Verification of cas no

The CAS Registry Mumber 1310893-65-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,8,9 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1310893-65:
(9*1)+(8*3)+(7*1)+(6*0)+(5*8)+(4*9)+(3*3)+(2*6)+(1*5)=142
142 % 10 = 2
So 1310893-65-2 is a valid CAS Registry Number.

Provided by the present invention are an anthraquinone colorant for coloring an ophthalmic lens represented by the following general formula (1): and a high molecular anthraquinone colorant obtained by forming a covalent bond between the anthraquinone colorant and a monomer for an ophthalmic lens. The monomer for an ophthalmic lens preferably has a polydimethylsiloxane structure. Further provided by the present invention is an ophthalmic lens material formed from a composition containing the colorant and a monomer for an ophthalmic lens having an unsaturated double bond, and the lens material containing a polymer comprising the monomer for an ophthalmic lens as a monomer unit.
