Check Digit Verification of cas no

The CAS Registry Mumber 253344-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,3,4 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 253344-98:
(8*2)+(7*5)+(6*3)+(5*3)+(4*4)+(3*4)+(2*9)+(1*8)=138
138 % 10 = 8
So 253344-98-8 is a valid CAS Registry Number.

, p. 1847 - 1849 (2008/02/11)

(formula presented) For practical applications of poled electrooptic polymers, highly efficient and thermally stable nonlinear optical (NLO) chromophores are required. We describe here a concise synthesis and characterization of a series of donor-acceptor
