193687-61-5 Usage
Uses
Since the provided materials do not specify the exact applications and usage of 2-[2-[2-Chloro-3-[2-(3-methyl-3H-benzthiazol-2-ylidene)-ethylidene]-1-cyclopenten-1-yl]ethenyl]-3-methyl-benzthiazolium, it is not possible to list its uses as per the given instructions. However, based on the information provided, it can be inferred that such chemicals are typically synthesized and studied for specific research purposes, or they may be intermediates in the synthesis of more complex compounds. To determine their exact applications, further research and information would be required.
Check Digit Verification of cas no
The CAS Registry Mumber 193687-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,6,8 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 193687-61:
(8*1)+(7*9)+(6*3)+(5*6)+(4*8)+(3*7)+(2*6)+(1*1)=185
185 % 10 = 5
So 193687-61-5 is a valid CAS Registry Number.

Page/Page column 12, (2008/06/13)
The object is to provide a novel nonsolvate-form crystal of polymethine compound which has good stability in solution, shows a high gram extinction coefficient, is excellent in storage stability, is easy to handle and is highly sensitive to general-purpose semiconductor lasers. Thus are provided a nonsolvate-form crystal of a polymethine compound of the formula (I) and a process for producing the nonsolvate-form crystal of polymethine compound of formula (I) which comprises reacting a polymethine ether compound of the formula (II) given below with p-toluenesulfonic acid. (In the above formula, TsO represents the p-toluenesulfonic acid residue.) (In the above formula, R represents an alkyl group, an alkoxyalkyl group or an optionally substituted aryl group.)
