21273-03-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21273-03-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,7 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21273-03:
(7*2)+(6*1)+(5*2)+(4*7)+(3*3)+(2*0)+(1*3)=70
70 % 10 = 0
So 21273-03-0 is a valid CAS Registry Number.

Mechanism of cyclohexanol dehydration catalysed by zirconium phosphate
Johnstone, Robert A.W.,Liu, Jun-Yao,Whittaker, David
, p. 1287 - 1288 (2007/10/03)
Deuterium-labelling studies have shown that dehydration of cyclohexanol to cyclohexene over amorphous zirconium phosphate at 350°C proceeds through a carbocation mechanism and not through a concerted process.
