19914-41-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19914-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,1 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19914-41:
(7*1)+(6*9)+(5*9)+(4*1)+(3*4)+(2*4)+(1*1)=131
131 % 10 = 1
So 19914-41-1 is a valid CAS Registry Number.

Fluorogenic peptide substrates for serine and threonine phosphatases

Xue, Fengtian,Seto, Christopher T.

supporting information; experimental part, p. 1936 - 1939 (2010/07/06)

Figure presented A new fluorescent assay for Ser/Thr protein phosphatases has been developed. Hydrolysis of a phosphoSer residue liberates the Ser hydroxyl group, which induces a cyclization reaction on the N-terminal carbamate and releases a fluorescent reporter. Sequence selectivity is observed using several peptide substrates against alkaline phosphatase (ALP), bacteriophage protein phosphatase (-PPase), and vaccinia H1 related phosphatase (VHR). These studies suggest that the assay could be a useful tool for profiling the substrate specificities of medicinally important phosphatases.
