1243671-55-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1243671-55-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,6,7 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1243671-55:
(9*1)+(8*2)+(7*4)+(6*3)+(5*6)+(4*7)+(3*1)+(2*5)+(1*5)=147
147 % 10 = 7
So 1243671-55-7 is a valid CAS Registry Number.

Synthesis of novel thiadiazoles and bis-thiadiazoles from carbonothioic dihydrazide
Sayed, Abdelwahed R.
supporting information; experimental part, p. 4490 - 4493 (2010/10/02)
Efficient syntheses of 1,3,4-thiadiazoles and bis-thiadiazoles by the reaction of hydrazonoyl halides with carbonothioic dihydrazide are reported. In addition, 1,2,4-triazolo[3,4-b][1,3,4]thiadiazole is obtained via oxidative cyclization of bis-(substitut
