Safety Profile
Questionable carcinogen. Whenheated to decomposition it emits toxic vapors of Clí.Check Digit Verification of cas no
The CAS Registry Mumber 39227-58-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,2 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.Calculate Digit Verification of CAS Registry Number 39227-58:
(7*3)+(6*9)+(5*2)+(4*2)+(3*7)+(2*5)+(1*8)=132
132 % 10 = 2
So 39227-58-2 is a valid CAS Registry Number.
