128293-94-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128293-94-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,9 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128293-94:
(8*1)+(7*2)+(6*8)+(5*2)+(4*9)+(3*3)+(2*9)+(1*4)=147
147 % 10 = 7
So 128293-94-7 is a valid CAS Registry Number.

When arylhydrazones of α-methyleneketones are treated with thionyl chloride they form 2-aryl-1,2,3-thiadiazolium chlorides in high yield, via the intermediate 1,2,3-thiadiazol-3-ine 1-oxides. The effect of substituents on the course of the cyclization was investigated.
