Check Digit Verification of cas no

The CAS Registry Mumber 20187-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,8 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20187-89:
(7*2)+(6*0)+(5*1)+(4*8)+(3*7)+(2*8)+(1*9)=97
97 % 10 = 7
So 20187-89-7 is a valid CAS Registry Number.

THERMOSTABLE BIOCATALYST COMBINATION FOR NUCLEOSIDE SYNTHESIS

-

Paragraph 0096-0097, (2016/08/17)

The present invention relates to a transglycosylation method for the preparation of natural and synthetic nucleosides using a uridine phosphorylase (PyNPase, E.C. 2.4.2.3), a purine nucleoside phosphorylase (PNPase, E.C. 2.4.2.1), or a combination thereof. These biocatalysts may be used as such, or by means of host cells transformed with vectors comprising recombinant DNA gene derived from hyperthermophilic archaea and encoding for the PyNPase and PNPase enzymes.
