Check Digit Verification of cas no

The CAS Registry Mumber 13182-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,8 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13182-75:
(7*1)+(6*3)+(5*1)+(4*8)+(3*2)+(2*7)+(1*5)=87
87 % 10 = 7
So 13182-75-7 is a valid CAS Registry Number.

Synthesis of Heterocycles. Part VII . Synthesis and Antimicrobial Activity of Some 7H-s-Triazolothiadiazine and s-Triazolothiadiazole Derivatives

Eweiss, N. F.,Bahajaj, A. A.

, p. 1173 - 1182 (2007/10/02)

The cyclization of 4-amino-5-aryl-3-cyanomethylthio-1,2,4-triazoles II in the presence of concentrated sulfuric acid yields 7H-6-amino-s-triazolothiadiazines III.Cyclization of 4-amino-5-aryl-1,2,4-triazole-3-thiones I with phenacyl chloride yields 7H-3-aryl-6-phenyl-s-triazolothiadiazines IV.Similarly, compounds I condensed with cyanogen bromide, phenyl isothiocyanate and carbon disulfide to give the corresponding cyclized products 6-amino-3-aryl-s-triazolothiadiazoles V, 3-aryl-6-phenylamino-s-triazolothiadiazoles VI and 3-aryl-s-triazolothiadiazol-6(5H)thiones VII, respectively.Also in the presence of phosphoryl chloride, compounds I underwent cyclization with monocarboxylic acids and oxalic acid to 3,6-diaryl-s-triazolothiadiazole VIII and 6,6'-bis(3-aryl-s-triazolothiadiazoles) IX.The above compounds were screened for their antimicrobial activity.
