104909-01-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104909-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,0 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104909-01:
(8*1)+(7*0)+(6*4)+(5*9)+(4*0)+(3*9)+(2*0)+(1*1)=105
105 % 10 = 5
So 104909-01-5 is a valid CAS Registry Number.
