53847-70-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53847-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,8,4 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53847-70:
(7*5)+(6*3)+(5*8)+(4*4)+(3*7)+(2*7)+(1*0)=144
144 % 10 = 4
So 53847-70-4 is a valid CAS Registry Number.

SYNTHESES AND CHELATING PROPERTIES OF AZOTHIOPYRINES
Tanaka, Tomoo,Tanaka, Kuniyuki
, p. 445 - 450 (2007/10/02)
Azothiopyrine and methyl-azothiopyrine were synthesized as new chelating agents which form stable chelates with some metal ions at the mercapto and azo groups.Azothiopyrines are unusually stable in solution because of a strong intramolecular hydrogen bond
