138457-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138457-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,5 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138457-85:
(8*1)+(7*3)+(6*8)+(5*4)+(4*5)+(3*7)+(2*8)+(1*5)=159
159 % 10 = 9
So 138457-85-9 is a valid CAS Registry Number.

Synthesis and cytotoxic activity of C-glycosidic nicotinamide riboside analogues
Krohn,Heins,Wielckens
, p. 511 - 517 (2007/10/02)
The C-glycosidic nicotinamide riboside analogue (2) was prepared by reaction of ribonolactone 24 with the lithiated oxazoline 19 followed by triethylsilane reduction to 26 and deprotection. Selective phosphorylation to the pseudonucleotide 34 was effected
