1104393-73-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1104393-73-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,4,3,9 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1104393-73:
(9*1)+(8*1)+(7*0)+(6*4)+(5*3)+(4*9)+(3*3)+(2*7)+(1*3)=118
118 % 10 = 8
So 1104393-73-8 is a valid CAS Registry Number.
