211-16-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 211-16-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,1 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 211-16:
(5*2)+(4*1)+(3*1)+(2*1)+(1*6)=25
25 % 10 = 5
So 211-16-5 is a valid CAS Registry Number.

Benzo[1,2-c:3,4-c′]bis[1,2,5]selenadiazole, [1,2,5]selenadiazolo-[3, 4-e]-2,1,3-benzothiadiazole, furazanobenzo-2,1,3-thiadiazole, furazanobenzo-2,1,3-selenadiazole and related heterocyclic systems

Cillo, Catherine M.,Lash, Timothy D.

, p. 955 - 962 (2007/10/03)

The first synthesis of benzo[1,2-c:3,4- c′]bis[1,2,5]selenadiazole has been developed starting from commercially available 4-nitrobenzo-2,1,3- selenadiazole. Improved syntheses of the related heterocycles [1,2,5]selenadiazolo[3,4-e]-2,1,3-benzothiadiazole, furazanobenzo-2,1,3- thiadiazole and furazanobenzo-2,1,3-selenadiazole are also reported.

MEHRFACH THIADIAZOL-UEBERBRUECKTE BENZOL- UND P-BENZOCHINON-RADIKALANIONEN UND IHRE Cr-, Mo- UND W-PENTACARBONYL-KOMPLEXE

Bock, Hans,Haenel, Peter,Neidlein, Richard

, p. 235 - 252 (2007/10/02)

Stable radical anions of bis(thiadiazolo)-p-benzoquinone as well as of bis- and tris(thiadiazolo)benzene derivatives form on one-electron reduction using potassium/ cryptand in THF solution.According to the assigned ESR spectra, their electron-rich sulfur centers exhibit especially large spin populations.On addition of THF soluble alkalimetal salts, the ESR signals vanish, whereas with metal hexacarbonyls Me(CO)6 paramagnetic mono- (Me = W) and di(metalpentacrbonyl) (Me = Cr, Mo, W) complexes result, for which HMO-McLachlan calculations suggest preferred coordination at the N centers of the same thiadiazol bridge.
