1195533-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1195533-03-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,5,5,3 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1195533-03:
(9*1)+(8*1)+(7*9)+(6*5)+(5*5)+(4*3)+(3*3)+(2*0)+(1*3)=159
159 % 10 = 9
So 1195533-03-9 is a valid CAS Registry Number.

Synthesis of 2-aminobutene-1,4-diones by gold-catalysed three-component coupling reactions
Liu, Li,Tang, Jiaqi,Qiang, Jian,He, Mingyang
, p. 247 - 249 (2016/05/19)
A gold-catalysed three-component coupling reaction of phenylglyoxal derivatives, alkynes and secondary amines was developed to provide a novel one-pot synthesis of 2-aminobutene-1,4-diones in moderate to good yields.
