64288-44-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64288-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,8 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 64288-44:
(7*6)+(6*4)+(5*2)+(4*8)+(3*8)+(2*4)+(1*4)=144
144 % 10 = 4
So 64288-44-4 is a valid CAS Registry Number.
