Check Digit Verification of cas no
The CAS Registry Mumber 157024-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,2 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 157024-19:
(8*1)+(7*5)+(6*7)+(5*0)+(4*2)+(3*4)+(2*1)+(1*9)=116
116 % 10 = 6
So 157024-19-6 is a valid CAS Registry Number.

Guanosine Derivatives Bearing an N2-3-Imidazolepropionic Acid
Heeb, Norbert V.,Benner, Steven A.
, p. 3045 - 3048 (1994)
Synthesis of a 2'-deoxyguanosine analog tethered through the exocyclic nitrogen via a 3 carbon chain to the 4-position of an imidazole is described.The imidazole forms a hydrogen bond with the 2'-hydroxyl group of a complementary cytosine bound as a Watson-Crick base pair.
