Check Digit Verification of cas no
The CAS Registry Mumber 188783-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,8 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188783-51:
(8*1)+(7*8)+(6*8)+(5*7)+(4*8)+(3*3)+(2*5)+(1*1)=199
199 % 10 = 9
So 188783-51-9 is a valid CAS Registry Number.

Convenient chemoenzymatic synthesis of β-purine-diphosphate sugars (GDP-fucose-analogues)
Baisch, Gabi,Oehrlein, Reinhold
, p. 383 - 391 (2007/10/03)
A series of peracetylated β-sugar-1-phosphates with L-fuco configuration are efficiently prepared chemically and coupled in high yields to purine monophosphate bases via imidazolide activation. The resulting purine diphosphate sugars are deacetylated comp
