Check Digit Verification of cas no

The CAS Registry Mumber 1232233-19-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,2,2,3 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1232233-19:
(9*1)+(8*2)+(7*3)+(6*2)+(5*2)+(4*3)+(3*3)+(2*1)+(1*9)=100
100 % 10 = 0
So 1232233-19-0 is a valid CAS Registry Number.

Rhodamine 6G fluorescent probe and preparation method thereof

-

Paragraph 0038; 0039; 0041; 0042, (2019/03/31)

The invention relates to the technical field of fluorescent probes, in particular to a rhodamine 6G fluorescent probe and a preparation method thereof. The specific scheme is as follows: the inventiondiscloses a structural formula of the rhodamine 6G fluorescent probe, and further discloses the specific preparation method which comprises the following steps: reacting rhodamine 6G with ethylenediamine to form an intermediate LDMO, then reacting the intermediate LDMO with o-vanillin, and recrystallizing to obtain the rhodamine 6G fluorescent probe. The fluorescent probe synthesized by the invention has the advantages that the synthesis process is simple, raw materials are easy to obtain, the reaction conditions are sample, the operation is simple and the yield is high; the fluorescent probeis highly selective to Fe among various common metal ions, and is not interfered by other common ions; the combination of Fe belongs to reactive recognition and is irreversible; and the target probe can be used for naked eye detection of Fe without the aid of any equipment.
