Check Digit Verification of cas no
The CAS Registry Mumber 133155-82-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,5 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133155-82:
(8*1)+(7*3)+(6*3)+(5*1)+(4*5)+(3*5)+(2*8)+(1*2)=105
105 % 10 = 5
So 133155-82-5 is a valid CAS Registry Number.

Ozonolysis of some 8-alkoxyquinolines, and synthesis of a precursor to the non-sedating antihistamine Claritin

, p. 38 - 53 (2015/01/08)
3-Formyl-2-methoxycarbonylpyridine and isopropyl 3-formylpyridine-2-carboxylate have each been efficiently accessed in one step via the ozonolyses of 8-methoxy- or of 8-isopropoxyquinoline under near-ambient conditions. The compounds can be utilized as intermediates for syntheses of the tricyclic ketone 8-chloro-6,11-dihydro-5H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-one, a precursor to the important non-sedating antihistamine Claritin.
