Check Digit Verification of cas no
The CAS Registry Mumber 7267-36-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,6 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7267-36:
(6*7)+(5*2)+(4*6)+(3*7)+(2*3)+(1*6)=109
109 % 10 = 9
So 7267-36-9 is a valid CAS Registry Number.

Conversion of imino-1,2,3-dithiazoles into 2-cyanobenzothiazoles, cyanoimidoyl chlorides and diatomic sulfur
English, Russell F.,Rakitin, Oleg A.,Rees, Charles W.,Vlasova, Olga G.
, p. 201 - 205 (2007/10/03)
Primary aromatic amines condense with 4,5-dichloro-1,2,3-dithiazolium chloride 1 to give high yields of the N-aryl imines 2 which on heating give 2-cyanobenzothiazoles 3, thus providing a simple two-step route to these heterocycles from the appropriate aniline. This thermolysis is favoured by electron donating substituents in the aniline ring, and retarded by electron withdrawing groups in favour of a second pathway in which both dithiazole sulfur atoms are lost to form cyanoimidoyl chlorides 4. This is the sole pathway when both aniline ortho positions are substituted. Analogous N-alkyl imines 5, prepared from the salt 1 and the bis(trimethylsilyl) derivatives of the amine, also decompose with loss of both sulfur atoms as singlet diatomic sulfur, S2. 4-Chloro-5-methylimino-5H-1,2,3-diathiazole 5a does this at 140-150°C and the S2 generated is intercepted with 2,3-diphenylbutadiene, 2,3-dimethylbutadiene and norbornene to give 16a, 16b and 17 respectively.
