Check Digit Verification of cas no

The CAS Registry Mumber 256660-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,6,6 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 256660-20:
(8*2)+(7*5)+(6*6)+(5*6)+(4*6)+(3*0)+(2*2)+(1*0)=145
145 % 10 = 5
So 256660-20-5 is a valid CAS Registry Number.

STILBENE DERIVATIVE, METHOD FOR PRODUCING THE SAME AND ELECTROPHOTOGRAPHIC PHOTORECEPTOR

-

Page/Page column 39-40, (2010/02/14)

PROBLEM TO BE SOLVED: To obtain a stilbene derivative that is hardly crystallized, has excellent compatibility with a binder resin and predetermined sensitivity not only at the early stage but also for many hours by having a triphenylamine structure containing a diphenylethenyl group in the molecule of a stilbene derivative, to provide a method for producing the same and to obtain an electrophotographic photoreceptor containing the stilbene derivative. SOLUTION: The stilbene derivative has a triphenylamine structure containing a diphenylethenyl group. The stilbene derivative is represented by formula (1) (R1, R2, R4-R10 and R12-R16 are each independently a 1-20C substituted or nonsubstituted alkyl group or the like; R3 and R11 are each a 1-20C substituted or nonsubstituted alkyl group or a 14-30C substituted or nonsubstituted diphenylethenyl group or the like; a repeating number A is an integer of 2-6). The electrophotographic photoreceptor comprises the stilbene derivative.
