303098-32-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 303098-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,0,9 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 303098-32:
(8*3)+(7*0)+(6*3)+(5*0)+(4*9)+(3*8)+(2*3)+(1*2)=110
110 % 10 = 0
So 303098-32-0 is a valid CAS Registry Number.

Preparation of aminals in water
Jur?ík, Václav,Wilhelm, René
, p. 3205 - 3210 (2007/10/03)
Aminals, which are used as protecting groups in syntheses and are part of many biologically active compounds, are normally prepared from aldehydes and diamines under conditions that remove water in order to shift the equilibrium to the side of the aminal.
