Check Digit Verification of cas no

The CAS Registry Mumber 1259953-64-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,9,5 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1259953-64:
(9*1)+(8*2)+(7*5)+(6*9)+(5*9)+(4*5)+(3*3)+(2*6)+(1*4)=204
204 % 10 = 4
So 1259953-64-4 is a valid CAS Registry Number.

An efficient synthesis of futalosine

Li, Xu,Tanner, Martin E.

scheme or table, p. 6463 - 6465 (2010/12/25)

Futalosine is a naturally occurring nucleoside comprised of an inosine core with a 3-carboxyphenyl methylene ketone functionality replacing the C-5′ hydroxyl. Recent studies have shown that it is a key intermediate in an alternative biosynthetic pathway that generates menaquinone in a variety of bacterial species. Here we report the first synthesis of futalosine in seven steps from inosine in an overall 17% yield. This work will enable further studies on menaquinone biosynthesis in pathogenic bacteria.
