Check Digit Verification of cas no
The CAS Registry Mumber 728918-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,8,9,1 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 728918-90:
(8*7)+(7*2)+(6*8)+(5*9)+(4*1)+(3*8)+(2*9)+(1*0)=209
209 % 10 = 9
So 728918-90-9 is a valid CAS Registry Number.

Deep UV photopatterning of biphenyl thiol self-assembled monolayer and its physical properties
Oh, Se Young,Kim, Hee Jeong,Choi, Hyung Seok
, p. 229 - 236 (2007)
Aromatic thiol such as a 4'-mercapto-biphenyl-4-carboxylic acid was synthesized, and then the self-assembled monolayer (SAM) was fabricated on a gold substrate. The pattern formation of biphenyl thiol and alkanethiol SAMs was obtained by oxidation reaction due to the irradiation of deep UV light. The resulting positive pattern image and current-voltage (I-V) characteristics of biphenyl thiol and alkanethiols were investigated through the measurements of Atomic Force Microscope (AFM) and Scanning Tunneling Microscope (STM). In addition, cytochrome c protein was immobilized onto the patterned gold substrate by self-assembly technique and electrochemical activity was studied with a cyclic voltammetry.
