Check Digit Verification of cas no

The CAS Registry Mumber 1846-31-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,4 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1846-31:
(6*1)+(5*8)+(4*4)+(3*6)+(2*3)+(1*1)=87
87 % 10 = 7
So 1846-31-7 is a valid CAS Registry Number.

Combinatorial discovery of novel fluorescent dyes based on Dapoxyl

Zhu, Qing,Yoon, Hai-Shin,Parikh, Puja B.,Chang, Young-Tae,Yao, Shao Q.

, p. 5083 - 5086 (2007/10/03)

We have developed a combinatorial method for the fast and effective synthesis of a library based on a known fluorescent dye, Dapoxyl using parallel solution-phase chemistry. By screening the 140 new compounds using fluorescence-based assays, we identified three new fluorescent dyes with novel properties.
