889664-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 889664-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,6,6 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 889664-41:
(8*8)+(7*8)+(6*9)+(5*6)+(4*6)+(3*4)+(2*4)+(1*1)=249
249 % 10 = 9
So 889664-41-9 is a valid CAS Registry Number.

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
