189075-80-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189075-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,7 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189075-80:
(8*1)+(7*8)+(6*9)+(5*0)+(4*7)+(3*5)+(2*8)+(1*0)=177
177 % 10 = 7
So 189075-80-7 is a valid CAS Registry Number.

Synthesis of quinazolinone analogues using sodium perborate as catalyst
Kidwai, Mazaahir,Priya
experimental part, p. 1876 - 1881 (2009/05/26)
An environmentally benign approach for the synthesis of 2-aryl-3H-quinazolin-4-ones employing sodium perborate (SPB) as catalyst is described. SPB in water and acetone system is proved as selective catalyst of hydration for cyanides. The rate enhancement
