A human poison. A
flammable liquid. When heated to
decomposition it emits toxic vapors of SOx
Check Digit Verification of cas no
The CAS Registry Mumber 1679-07-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1679-07:
(6*1)+(5*6)+(4*7)+(3*9)+(2*0)+(1*7)=98
98 % 10 = 8
So 1679-07-8 is a valid CAS Registry Number.
