444759-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444759-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,7,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 444759-99:
(8*4)+(7*4)+(6*4)+(5*7)+(4*5)+(3*9)+(2*9)+(1*9)=193
193 % 10 = 3
So 444759-99-3 is a valid CAS Registry Number.
