441067-91-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 441067-91-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,1,0,6 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 441067-91:
(8*4)+(7*4)+(6*1)+(5*0)+(4*6)+(3*7)+(2*9)+(1*1)=130
130 % 10 = 0
So 441067-91-0 is a valid CAS Registry Number.
