944480-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 944480-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,4,8 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 944480-99:
(8*9)+(7*4)+(6*4)+(5*4)+(4*8)+(3*0)+(2*9)+(1*9)=203
203 % 10 = 3
So 944480-99-3 is a valid CAS Registry Number.
