332419-75-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 332419-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,2,4,1 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 332419-75:
(8*3)+(7*3)+(6*2)+(5*4)+(4*1)+(3*9)+(2*7)+(1*5)=127
127 % 10 = 7
So 332419-75-7 is a valid CAS Registry Number.

Studies on aroylation of 2,3-pyridinediamines
Dubey,Vinod Kumar
, p. 746 - 751 (2007/10/03)
The reaction of 2,3-pyridinediamine 1a and its 5-bromo analogue 1b, independently, with acid chloride or anhydride does not yield the diaroyl derivative and instead yields the cyclised product 3 or the monoaroyl derivative 4 depending upon the conditions.
