444809-32-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444809-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,8,0 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 444809-32:
(8*4)+(7*4)+(6*4)+(5*8)+(4*0)+(3*9)+(2*3)+(1*2)=159
159 % 10 = 9
So 444809-32-9 is a valid CAS Registry Number.
