Check Digit Verification of cas no
The CAS Registry Mumber 4431-74-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4431-74:
(6*4)+(5*4)+(4*3)+(3*1)+(2*7)+(1*4)=77
77 % 10 = 7
So 4431-74-7 is a valid CAS Registry Number.

We have explored a novel molecular framework with a lysine core to prepare a probe library for protein kinases. Active site-directed probes, identified through screening of the library, displayed desirable labelling properties, including target specificity, good linear response to the corresponding enzymatic activity and cell permeability. Finally, a two-stage protocol utilizing the newly developed probe with an immunoprecipitation step was successfully established to monitor intracellular Src kinase activity in RK3E-v-Src cells.
