104441-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104441-43-2 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 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104441-43:
(8*1)+(7*0)+(6*4)+(5*4)+(4*4)+(3*1)+(2*4)+(1*3)=82
82 % 10 = 2
So 104441-43-2 is a valid CAS Registry Number.
