40139-59-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40139-59-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,3 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40139-59:
(7*4)+(6*0)+(5*1)+(4*3)+(3*9)+(2*5)+(1*9)=91
91 % 10 = 1
So 40139-59-1 is a valid CAS Registry Number.

Ring Transformation of 3-Hydroxy-1,2,5- and -1,2,4-thiadiazoles and -isothiazoles into Isothiazole , Thiazole and Thiophene Derivatives

Mataka, Shuntaro,Takahashi, Kazufumi,Tashiro, Masashi

, p. 1496 - 1502 (2007/10/02)

Ring transformation of 3-hydroxy-1,2,5-thiadiazole (1), 3-hydroxy-1,2,4-thiadiazole (14), and 3-hydroxyisothiazole (18) by the reaction with acetic anhydride in the presence of DBU afforded isothiazoles 2-5 and 13, thiazoles 15 and 16 and thiophenes 21-25, respectively.The reaction of 1 with propionic anhydride gave isothiazole 13.The formation pathway of the products is mentioned.
