104239-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104239-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,3 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104239-08:
(8*1)+(7*0)+(6*4)+(5*2)+(4*3)+(3*9)+(2*0)+(1*8)=89
89 % 10 = 9
So 104239-08-9 is a valid CAS Registry Number.
