Check Digit Verification of cas no

The CAS Registry Mumber 204689-15-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,6,8 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 204689-15:
(8*2)+(7*0)+(6*4)+(5*6)+(4*8)+(3*9)+(2*1)+(1*5)=136
136 % 10 = 6
So 204689-15-6 is a valid CAS Registry Number.

Self-assembled organogels based on two-component system

Nam, Seong Ryong,Lee, Ho Yong,Hong, Jong-In

, p. 10531 - 10537 (2008)

Organogels were produced by the self-assembly of two organogelators, 3,5-bis(dodecanoylamino)benzoic acid and aromatic amines, in nonaromatic hydrocarbon solvents, through hydrogen bonding, aromatic stacking, and van der Waals interactions. 3,5-Bis(dodecanoylamino)benzoic acid has one carboxylic acid group for hydrogen bonding with amines and two alkylamide groups that can participate in interlayer hydrogen bonding and van der Waals interactions. The shape and size of the aromatic amines have a significant effect on the gel properties as well as their structures. A variety of organogels were realized by forming complexes of 3,5-bis(dodecanoylamino)benzoic acid and various amines with an aromatic group in nonaromatic hydrocarbon solvents.
