864444-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 864444-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,4,4 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 864444-89:
(8*8)+(7*6)+(6*4)+(5*4)+(4*4)+(3*4)+(2*8)+(1*9)=203
203 % 10 = 3
So 864444-89-3 is a valid CAS Registry Number.
