Check Digit Verification of cas no

The CAS Registry Mumber 1610517-71-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,0,5,1 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1610517-71:
(9*1)+(8*6)+(7*1)+(6*0)+(5*5)+(4*1)+(3*7)+(2*7)+(1*1)=129
129 % 10 = 9
So 1610517-71-9 is a valid CAS Registry Number.

Phospho-carboxylic anhydride of a homologated nucleoside leads to primer degradation in the presence of a polymerase

Kachare, Dhuldeo,Song, Xiao-Ping,Herdewijn, Piet

supporting information, p. 2720 - 2723 (2015/02/19)

Starting from thymidine, through a series of key synthetic transformations (e.g., Wittig reaction, hydroboration, Mitsunobu reaction and TEMPO oxidation) a nucleoside homologue bearing a phospho-carboxylic anhydride group at 6′ position was synthesized. The potential of polymerases to catalyze amide bond formation was investigated by using a modified primer with an amino group at 3′ position and the synthesized phosphoanhydro compound as substrate. Unfortunately, we did not observe the desired product either by gel electrophoresis or mass spectrometry. In contrast, the instability of the phosphoanhydro compound could lead to pyrophosphate formation and thus, to pyrophosphorolysis of the primer rather than to primer extension.
