909777-15-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909777-15-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,7,7 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 909777-15:
(8*9)+(7*0)+(6*9)+(5*7)+(4*7)+(3*7)+(2*1)+(1*5)=217
217 % 10 = 7
So 909777-15-7 is a valid CAS Registry Number.

Sensing metal ions with DNA building blocks: Fluorescent pyridobenzimidazole nucleosides
Kim, Su Jeong,Kool, Eric T.
, p. 6164 - 6171 (2006)
We describe novel fluorescent N-deoxyribosides (1 and 2) having 2-pyrido-2-benzimidazole and 2-quino-2-benzimidazole as aglycones. The compounds were prepared from the previously unknown heterocyclic precursors and Hoffer's chlorosugar, yielding alpha ano
