190957-78-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 190957-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,9,5 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 190957-78:
(8*1)+(7*9)+(6*0)+(5*9)+(4*5)+(3*7)+(2*7)+(1*8)=179
179 % 10 = 9
So 190957-78-9 is a valid CAS Registry Number.

Furopyridines. XXVI [1]. Reactions of cyanopyridine derivatives of furo[2,3-b]-, -[3,2-b]-, -[2,3-c]- and -[3,2-c]pyridine

Yamaguchi, Seiji,Saitoh, Hideo,Kurosaki, Masahide,Yokoyama, Hajime,Hirai, Yoshiro,Shiotani, Shunsaku

, p. 1 - 9 (2007/10/03)

Bromination of α-cyanopyridine derivatives of furopyridines 1a-d gave the 2,3-dibromo-2,3-dihydro compounds 2a-d in excellent yields. Treatment of 2a-d with sodium hydroxide in methanol yielded compounds formed through the dehydrobromination and solvolysis of the nitrile. N-Oxidation of 1a and 1b gave N-oxide in much poor yield, while 1c and 1d gave the N-oxide 13c and 13d in good yields. The nucleophilic reactions (cyanation, chlorination and acetoxylation) of 13c and 13d through a Reissert-Henze type reaction gave poor results, which would be caused by the strong electron withdrawing effect of the cyano group.
