189346-46-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189346-46-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,4 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 189346-46:
(8*1)+(7*8)+(6*9)+(5*3)+(4*4)+(3*6)+(2*4)+(1*6)=181
181 % 10 = 1
So 189346-46-1 is a valid CAS Registry Number.

Synthesis of bicyclic enediynes that possess a photosensitive triggering device and exhibit strong DNA cleaving activity

supporting information; experimental part, p. 5942 - 5944 (2010/10/21)

The synthesis of a bicyclic enediyne capable of photosensitive triggering and conjugated to a pyrrole-imidazole polyamide is described. Using UV irradiation, this hybrid molecule is shown to exhibit 100-fold stronger potency for DNA cleavage, in an in vitro assay, as compared to the enediyne without the DNA-localizing pyrrole-imidazole.
