208186-86-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 208186-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,1,8 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 208186-86:
(8*2)+(7*0)+(6*8)+(5*1)+(4*8)+(3*6)+(2*8)+(1*6)=141
141 % 10 = 1
So 208186-86-1 is a valid CAS Registry Number.

Cholinesterase reactivators derived from pyridine-2-carbaldoxime

Bielavsky, Jiri,Kassa, Jiri,Elsnerova, Iva,Dejmek, Lubos

, p. 199 - 204 (1998)

Monoquaternary reactivators of cholinesterase 3a-3c were prepared by quaternization of substituted pyridine-2-carbaldoximes with an ester (1a, 1b) or carbamoyl (2) function in position 4. A new bisquaternary reactivator, 4-carbamoyl-2′-[(hydroxyimino)methyl]-1,1′-(but-2-ene-1,4-diyl) bispyridinium salt (5), was derived from the unsubstituted pyridine-2-carbaldoxime. The compounds were characterized by UV spectra and ionization constants. The substances exhibit antidote effects in intoxications with organophosphate cholinesterase inhibitors.
