Check Digit Verification of cas no
The CAS Registry Mumber 193624-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,6,2 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 193624-86:
(8*1)+(7*9)+(6*3)+(5*6)+(4*2)+(3*4)+(2*8)+(1*6)=161
161 % 10 = 1
So 193624-86-1 is a valid CAS Registry Number.

Chlorination of the N-oxides of furo[2,3-b]- 1a, -[2,3-c]- 1b and -[3,2-c]pyridine 1c with phosphorus oxychloride afforded compounds substituted normally at the α- or γ-position to the ring nitrogen, 2a, 2′a, 2b, 2c, 2′c and 2″c, and in addition, in the case of 1b, compounds substituted on the furan ring, 2′b and 2″b. The structures of these compounds were confirmed from their ir, nmr and mass spectra. The major chlorinated products 2a, 2b and 2c were converted to methoxy- 5a, 5b and 5c, N-pyrrolidyl- 7a, 7b and 7c, and phenylthiofuropyridines 8a, 8b, and 8c.
