Check Digit Verification of cas no

The CAS Registry Mumber 181526-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,5,2 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 181526-20:
(8*1)+(7*8)+(6*1)+(5*5)+(4*2)+(3*6)+(2*2)+(1*0)=125
125 % 10 = 5
So 181526-20-5 is a valid CAS Registry Number.

Furopyridines. XIX [1]. Reaction of furo[2,3-b]-, -[3,2-b]-, -[2,3-c]- and -[3,2-c]pyridine with acetic anhydride

Shiotani, Shunsaku,Taniguchi, Katsunori,Ishida, Toshimasa,In, Yasuko

, p. 647 - 654 (1996)

Acetoxylation of N-oxide of furo[2,3-b]- 2a, -[3,2-b]- 2b, -[2,3-c]- 2c and -[3,2-c]pyridine 2d with acetic anhydride afforded compounds substituted normally at the α- or γ-position to the ring nitrogen, 3a, 4a, 4b, 3d, 4d, 8 and 9, and in addition compounds substituted on the furan ring, 5a, 6a, 5b, 6b, 7b, 5c and 7c which were unexpected compounds. The structures of these compounds were established from the ir, nmr and mass spectra, and x-ray crystal analysis of 5b.
