104445-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104445-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,4 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104445-68:
(8*1)+(7*0)+(6*4)+(5*4)+(4*4)+(3*5)+(2*6)+(1*8)=103
103 % 10 = 3
So 104445-68-3 is a valid CAS Registry Number.
